NS,
Mmm except he is here starting a discussion about people being insulting and in the OP where he says he is opposed to it, insults people. Should the hypocrisy in that be ignored?
Sort of. I’m fairly relaxed about his hypocrisy – it’s the old thing about the statement “murder is wrong” not being invalidated if it’s said by a murderer. That the speaker doesn’t follow his own advice says nothing to whether or not that advice is sound.
What is legitimate though is to point out where he commits a logical fallacy – in this case the
ignoratio elenchi: he complains about swearing, but whether he’s right or wrong to do so is irrelevant to his complaint in the OP.
As it happens the OP fails in any case because BA (or the quote of which he approves) wrongly conflates attacking the argument with attacking the person who holds the argument dear, and he seems now to be trying to make us look the other way about that by introducing something else.
