Coach Matt O'Connor's has fired off significant shots at critics who see Leinster as a force without form.
"How do you guys categorise form?" he asked the written media.
"Is it winning games? Is it scoring tries? We've scored the most tries in the League."
He will not countenance a return to former inglorious times when Leinster were all flash and no substance.
"Five or six years ago, Leinster were playing a tremendous brand of rugby, slinging the ball around, a fantastic brand of rugby," he said.
"What were the press saying then? Ladyboys. Soft."
The Australian views the game in simple, straight-forward terms.
"Our philosophy is finding a competitive advantage against the opposition to win the game. That's our style of rugby."
And he also indicated Leinster would look to turn the screw on Harlequins' forwards in The Champions Cup at The Stoop on Sunday.
"We've got a test pack that will go out on Sunday. What's your competitive advantage relative to the opposition?"
Meanwhile, an all-Ireland bid to stage the 2023 Rugby World Cup is set to be officially unveiled.
Officials from the IRFU will today join representatives from the Northern Ireland Executive and Irish government to outline their ambition to jointly host the sport's showpiece event.
Both administrations have been engaged in a preliminary assessment exercise over the last 10 months to weigh up the feasibility of submitting an official bid.
