What a joke of an article in New York magazine. Its premise is that casual same-sex hooking up is a big deal in high schools; bi-sexuality is now very gray; adults are standing by passively, etc. I also loved the quote by the professor who’s "been studying same-sex attraction among adolescents for more than 20 years." Sounds like a great field to be conducting scholarly research.
The meta point that, due to the ubiquity of contraceptives and sex education, casual hooking up/sex has increased among teens while official dating has decreased is true, in my view. But this does not mean we have a culture where teens "kiss anything that is beautiful" and whatnot.
The more serious point in all this is what effects, if any, growing up in a pornified culture will have on the next generation of leaders. Too bad this article went the easy route of picking scandalous quotes from teens which will further the cause of every worry-mom.
