"'If you’re talking to a man who wouldn’t fight with you under any circumstances whatsoever, then you’re talking to someone to whom you have absolutely no respect'
I am absolutely astounded by this. If he was talking to Stephen Hawking he would have absolutely no respect for him? How about Ghandi?
What a bizarre thing to say."
You seem to have misquoted/out of context.
" when men are talking to each other in any serious manner, that underlying threat of physicality is always there, especially if it’s a real conversation. It keeps the thing civilized to some degree. If you’re talking to a man who wouldn’t fight with you under any circumstances whatsoever, then you’re talking to someone [for] whom you have absolutely no respect. "
i.e. that the risk of being punched in the face greatly informs male-male interactions and engenders some degree of respect.
I don't think this has anything to do with Gandhi or Stephen Hawking, but rather an acknowledgment that violence is an inherently masculine trait.
