One thing I will say about the video and the "OMG, I can't even say hi to a girl anymore!" thing ... the thing is most of the guys in the video aren't saying just "hi".
If I come into your house and say "hi" to your mom, I'm sure you'd be OK with that.
If I come into your house and "hey baby" and then glare at her ass and say "Mmmmm, you look good today" ... I don't think most people would be OK with that.
"Hi" and the above is not the same thing.
I know some guys will say "well I wouldn't mind if women complimented me" ... would you also be just fine with gay men leering at you, following you around, saying "mmm and hey stud" as you walk past?
That said, I think women need to understand too that they're aren't men, and things are never going to be 100% equal in this regard. They hold many advantages in the male-female dynamic when it comes to relationships and sex ... hey it's not fair that decent-to-good looking women get ushered to the front of the line at nightclubs and other events, but it is what it is. It's not fair that men have to be the ones that generally approach and deal with issue of getting rejected, whereas women can basically sit back and "audition" guys.
But I will say yeah, I can see a woman's POV here that getting cat called while just walking down the street would get annoying and highly uncomfortable after a while. I'm not sure what can be done about it. Some men just play a numbers game where they will have to try and interact (no matter how crude the fashion is) with every attractive woman they see.
