I have seen / heard of many guys getting complimented over the years (including myself a few times), and never heard of one of them turning into a “psycho”, “asshole”, or ”monster”. A couple times I saw a guy get complimented out of the blue and then kind of stammer something and hurry away looking embarrassed, because he didn’t have any idea how to respond. A couple times I have seen men brush off / refuse compliments it looked like because they wanted to seem modest (e.g. “oh it was really no big deal, please don’t think anything of it...” after someone had just directly said their action was very helpful/meaningful). Once I saw a guy get complimented and respond “yeah, everyone says the same thing”, which I admit is a pretty obnoxious response.
I have also heard plenty of stories of guys who were monsters (physical abusers, stalkers, spreaders of nasty rumors ...), but to my knowledge none of those came out of a compliment.
I believe you, but I’m having trouble imagining quite what happened. Maybe you can elaborate a bit? Do you mean that those men turned around and demanded something more from you? Stopped treating you with basic respect? Wouldn’t talk to you anymore? Chased you around? ...
