Peter O’Mahony admitted he took offence over a line of questioning in the immediate aftermath of their Guinness Pro14 defeat to Leinster.
Munster went down 23-17 and scored three tries, all from distance, but Leinster held the upper hand for the majority of the tie.
Former Leinster and Ireland prop Reggie Corrigan spoke to the Munster captain after the game for TG4, asking if he felt O’Mahony’s team-mates had given everything to the game.
"I think it’s a silly question," said the Lions flanker.

"Essentially he’s calling myself and my team-mates out, saying we’re not trying hard enough, questioning are we working hard enough and do we want it enough.
"I’m a very proud man, a very proud Munster man, a very proud Irish man and that’s a question of the core of everything.
"Everything we do in Munster rugby and Irish rugby is based around work-rate and your want to win and how relentless you can be and for someone to question that I’d take huge offence to."
O’Mahony was also keen to point out how some off the pre-match talk was way off the mark.
Director of rugby Johan Erasmus had described it as a "great training match" ahead of the next fortnight’s Champions Cup ties.
He added: "It’s a good lesson for us. There was talk this week about this game being not as big as it was.
"I think you certainly saw today the intensity, the skill levels, how hard people were trying, that it’s far from a training match."
Munster travel to Castres next weekend and O’Mahony says lessons must be learned from the defeat if they are to prosper in France.
"Discipline is a hugely important thing when you go away in France to give you a chance to win a game," he said.
"We saw from today that if we don’t get that right we’re going to be in big trouble.
"I don’t know what our final (error) tally, it was in the teens anyway was but you are always going to struggle against a team of that quality.
"As you can see we were trying different things, we’re trying hard.
"We really are working as hard as we can but you’ve got to give yourself a chance and we didn’t today with our display.
"You’re going to be under pressure if you keep conceding penalties. We found ourselves in our own territory a huge amount having to exit.
"We spent a lot of the game in our half and had very few set-pieces inside Leinster’s half, 22. Certainly [we only had] two or three opportunities for us."
