Last Sunday, Jon Williams, managing director RTÉ News, tweeted: "Not for first time, Eoghan Harris wrong. One day's decline in #Covid19 not a cause to cheer or despair. About trend. Not RTÉ's job to do either."
Now I believe that RTÉ's coverage of Covid is demonstrably unbalanced, creates a climate of fear and undermines the Government's gallant attempt to strike a balance between possible deaths from Covid and the almost certainly higher number of deaths caused by lockdowns.
But that aside, I believe that no matter what I write about, the head of news in RTÉ should not use Twitter as a bully pulpit to take me to task for two reasons.
First, Jon Williams has no right to reprimand me about anything for the simple reason I have no access to or right of reply on RTÉ.
Second, his opening, "Not for first time Eoghan Harris wrong", has a personal edge to it and is not supported by the facts.
I wasn't wrong about RTÉ big beasts bigging up Michael Heney's Arms Trial book whose thesis Des O'Malley demolished in the Sunday Independent.
I wasn't wrong about David McCullagh's histrionics in interviewing Micheál Martin, which I also wrote about recently.
I wasn't wrong to raise the wisdom of RTÉ showing Sean Murray's film, Unquiet Graves. But I imagine my criticisms irritated Jon Williams.
I am told Jon Williams is a nice guy. I can well believe it. He reached out to me some time ago to suggest we have a chat.
I didn't take up his offer. Like George Orwell, I find it hard to be hard on anyone once I've met them and I wanted to be free to criticise his conduct of RTÉ News should the need arise in the future - as it did on Covid.
Even now, despite the dismissive tone of his tweet, I find it hard to be hard on Jon Williams. He comes from a Liverpool Irish background which may have given him a more romantic view of Irish history than my more critical version.
When he arrived in RTÉ in 2016, I doubt he heard any good things about me from some of his colleagues who subscribe to RTÉ's political culture with its myopic soft spot for Sinn Féin's politics.
Indeed, Williams's arrival in RTÉ reminded me of an English clergyman appointed to a West Cork Church of Ireland parish.
Arriving with peace processing views of Irish history, he would not fully understand his congregation's lack of enthusiasm for nationalist centenaries stretches from the Dunmanway massacre of 1922 to bad experiences during H Blocks in 1981.
Last week, I doubt Williams's colleagues pointed out the courage of Chris Fitzpatrick, a consultant surgeon who, writing in the Irish Times, challenged the heroising of Kevin Barry.
"Like Barry, I was a devout Catholic, played hurling, and was a republican. If there'd been a war against the British in Dublin when I was at school, I'd have joined up, and if I was shot or hanged, that would've been OK, because martyrs went straight to heaven - like Kevin Barry did. That's what the Christian Brothers taught us in school, long before jihad was a word any of us had ever heard of."
Citing a study by Diarmaid Ferriter, Chris Fitzpatrick explained his ethical problems with the deaths of three young British soldier aged between 15 and 20 years.
"The significance of a medical student's involvement in the deaths of Harold Washington, Marshall Whitehead and Thomas Humphries troubles me greatly, as well as the deaths themselves - a chilling fact that is commonly overlooked."
He adds: "In the annals of medical history, it's rare to come across a medical student who sets out to kill another person."
But at least Jon Williams has the courage to challenge me openly. There are others in RTÉ who prefer to lurk in the shadows rather than defend their failure to show films that would lower rather than raise the tribal temper in the Republic.
Why don't the editors responsible come forward and explain why RTÉ has not shown balanced documentaries like Spotlight on the Troubles or Cops on the Frontline - decisions for which I stress Jon Williams has no responsibility.
Counterpoint RTÉ's failure to show balanced BBC films with its decision to show a partisan film like Unquiet Graves.
What conclusion can any reasonable person reach except that RTÉ has a political culture that is far too close to Sinn Féin's politics for comfort?
Far from cultivating the Republic's moral revulsion against IRA atrocities, RTÉ's output on the War of Independence centenaries seems designed to raise the tribal temperature.
Do the station chiefs ever stop to consider the impact of a constant stream of nationalist necrophilia on young minds?
Surely they can see that bloody stream has two downsides? First, it promotes in young minds a perpetual sour Anglophobia, often based on bad history, that makes them vulnerable to the Recurring IRA.
Second, it erodes the ethical anger most Irish people feel for the torturers of Paul Quinn and Tom Oliver and allows allegedly educated people to vote for Sinn Féin.
History does not repeat itself. But it is impossible not to be struck by some similarities between the rise of the German fascist party and the self-styled "left populists" of Sinn Féin.
Both were linked to armed militias, both targeted outsider groups - Jews or unionists - and both use coarse, shameless, violent language.
Ann Travers, whose sister was shot dead in front of her while leaving mass during an IRA attempt to murder her father, a Catholic magistrate, is regularly subjected on Twitter to the most disgusting trolling from SF supporters, including a recent one wishing she'd been shot, too.
I was born and raised a republican, not a West Brit. The reason I fear Sinn Féin is not because I'm a unionist but because I'm an Irish patriot and I believe it is a tribal party corrupting the Irish Republic.
That is one of the reasons I welcomed Paschal Donohoe's brilliant Budget, a gale of money that blew Sinn Féin off its feet.
Mary Lou McDonald greeted most of the Budget through gritted teeth, claiming Sinn Féin would have spent more. Pearse Doherty weakly complained the Budget didn't provide "certainty". But when have we certainty in this life?
Mary Lou McDonald was too depressed even to raise the Budget at Wednesday's Leader's Questions. Last Friday, pressed by Bryan Dobson for a straight answer on whether she favoured a move to Level 5, she turned into Mary Lou McWaffle.
There was also a welcome edge to Paschal Donohoe on last Tuesday's Prime Time.
He was arrestingly pugnacious in telling Pearse Doherty he was tired of hearing Sinn Féin's "single transferable speech".
This pugnacity is vital to stop the Sinn Féin habit of steamroller soliloquies.
Finally, factor in a Belfast Telegraph poll showing Colum Eastwood of the SDLP is the highest-rated political leader in Northern Ireland - Michelle O'Neill of SF being the lowest.
In sum, Paschal Donohoe's 'People's' Budget marked a good week for Irish democracy.
