I don't hate men, I hate abuse, misogyny, chauvinism, sexism, feminine socialisation etc.
Most men are great, but for example, you say the guys were all dressed smartly? I'd inevitably end up wondering, did the wives do their laundry, ironing and possibly shoe polishing for them? Because in most of the relationships I know, the woman does all that.
I've had a few male friends over the years that I eventually distanced myself from, when I started learning more about them, and certain attitudes/expectations they had. I was just a mate, and often seen as one of the boys, but rarely as gf/wife material, or even fuck buddy material.
Also, my ex was a charming bastard, the life and soul of the party, not a nasty word to say about anyone, great sense of humour, great taste in clothes. But he was a completely different man once he got home, especially when he'd been out drinking and acting Mr. Wonderful. It wasn't until we broke up, and he starting taking his shit out on friends (much lower level though), that people started to get a glimpse of the real him. Sorry my point is, even if someone (male or female), seems lovely, you can never truly know what goes on behind closed doors. One of the big issues women have, is not being believed, "he would never do that".
I know a few pervs (much older than me), who like to wait until they're alone with me, before being inappropriate. One guy in work (married, with a dd who's older than me), waits until we're in the cctv blind spots, to rub my back in a seemingly re-assuring way (I just know he's feeling to see if I'm wearing a bra, which I'm usually not). Sometimes he hugs me, or tries to kiss my cheek
