Aye the US beer pong loving, whooping, red cup plastic drinking dousch is a common theme in some of the more...trashier American films that make it over here.
It does seem to share similiar characteristics to this British phenomonon.
The particular problem that this report always comes back to is the problem with attitudes to the fairer sex. For instance:
(From the last point of the quoted section in the OP)
Anything like this happen? I can validate the groping, the last time i went to a nightclub the ladies loved grabbing Quackers. Whilst I was ok with it (Flattering) I imagine a woman wouldn't..Who knows?! Maybe if your a good looking male you can get away with that!
The ladies don't jump all over Antilogic, and he's not about to try coping a feel because he doesn't like drinks thrown in his face.

Depends on how common you consider it to be in the movies. It certainly isn't like everyone is part of it, at least at most universities. On the other hand, most universities have at least somewhat of a frat boy culture - how much varies widely. And even where the frats aren't as influential, some elements of that culture may be present outside of the frats. For example, you may have people who have nothing to do with organized fraternities or sororities playing beer pong and drinking from red Solo cups.
American universities do rather run the gamut on this, though. Washington and Lee down in Virginia has 90% of its students in fraternities or sororities; they probably aren't as rowdy as what you'd find at, say, Ohio University, but that's still going to leave a big frat boy culture. Then you have universities without any fraternities or sororities, and everything in between.
My university had about 40% of its students in fraternities or sororities, and while I didn't have much to do with them and few of my friends were in one, they certainly had a substantial influence on the weekend entertainment culture. How "laddish" they were, I'm not really sure, as I mostly avoided them. They did have heavy alcohol consumption; the other "laddish" traits probably varied by the fraternity. A couple of the more infamous ones had been de-certified shortly before or while I was there (although at least one of those continued to exist unofficially).
How to solve the issues? I'm not really sure; I'm not familiar enough with the mindset of those who are in that culture.
Definitely true.
If I had to guess without the benefit of data available, I think the frat boy culture is more heavy these days on the drinking and the social scene and not on the rampant hating, but it probably varies by school. At GT, we did have a frat infamously known as The Date-Rape Frat.
