well flavio, I can only say what I see ...
true, you're not "attacking" him verbally ... but you continue to talk circles around his responses ... breaking down every last thing he says ... and that can be frustrating - for some people, that's even more frustrating than being verbally attacked. I must say though, the comment about him continuing to remain celibate for the good of society I consider to be a personal attack.
He does say time and time again that these are his opinions ... your continuing to question the validity of such opinions gives one the impression that you are indeed attempting to change his opinion.
But that's just my opinion.
