Interesting stories Lua. These men are so different from myself I find their acts to be abnormal. Although I admit I am very shy so have never done anything like them in public. Heck building up towards even asking for a number take me awhile never mind asking a complete stranger for her number
And that's what really sucks about it. If I knew that this guy who I engaged with was going to be one who threatened me, then I'd like to walk on by, or if I knew that this guy was a total asshole and has just been sitting there all day shouting at women, I wouldn't stress it too much.
But then there's the guys who are super shy and forcing themselves to just get out of their comfort zone and ask a girl they think is cute out, and I'd feel like the biggest jerk in the world if I was aloof with them, and now, for obvious reasons, I have to reject them all, and it makes me feel terrible anyway. But it's hard not to get jaded if you deal with this all the time.
I think everything would be a lot easier for everyone if we could remove the cultural perception that it's normal for a guy to stop and remark on every girl who walks by that he thinks is attractive, and that the girls now owe them acknowledgement and attention. Get those guys to chill the fuck out. That should help a lot.
