Why can’t some people accept that all genders can be weird?

Sorry you went through that, I'm glad to hear you got out of the situation. All people can be anything like you said. I once had the bad luck of meeting someone that was walking around a bar walked up behind me where I was sitting and she reached around and grabbed me by the crotch, I had never seen her before that. I asked why she did that and she responded that she didn't want to waste her time talking to anyone and be disappointed later. To which I said please don't do that again and I went and told the bouncer because I saw her do it to another man as I walked away. The bouncer said he'd keep an eye out for it, because me telling him wasn't enough to address it apparently. Another time I had a woman walk up behind me while standing in line for the bathroom and reach between my legs from behind and grab my balls. I gave a wtf look and walked out of the place. It is far more common we hear about men acting like pigs, but anyone can act like one. Those were just the first 2 I thought of.

You're only lucky to be treated like that if and only if you wanted it, and made that desire obvious.

They should have stopped the moment you said no. Anything further is sexual harassment.

Consent is just as important online as in person, and sex/gender doesn't change anything.
