The kind of guy that joins a fraternity is not the kind of guy I want to make friends with.
Even though I don't associate myself with the Greek life, I personally think this post comes off as offensive to anyone who is a part of it. It's just like saying "The kind of guy that plays Pokemon is not the kind of guy I want to make friends with." The crowd one chooses to associate themselves with does not reflect on their character; this is an annoying, immature high school mentality and I wish everyone in the world would grow up out of this godforsaken way of plundering people into ridiculous stereotypes that account for virtually nobody.
In regards to Greek life, the OP and I are very good friends and he has discussed the benefits of it, which makes it seem like an interesting opportunity. Yes, there are the pitfalls of the typical fraternity; people join on the basis of what they know about Greek life, which is what's portrayed in the media; a bunch of preppy/jocky overtanned guidos getting laid and wasted. But when you look outside the narrow-minded view of the media and see that Greek life is more than its stereotype, you see that it becomes less about parties and girls and more about a unit, and the educational benefits of joining a fraternity.
I mean, I used to think the same as 90% of the people who've posted in this thread; "eww, parties where people get stupidly drunk, nothx"; but Akio here has shown me that it's more than that. I know it's easy for some to discredit Greek life based on the people who are a part of it, but in general, it as a whole can really benefit your college experience (And no, I don't mean the amount of women you sleep with.)
Still, even taking it into consideration, I have to say I wouldn't join. I've had my share of being the oddball of the group, and I can safely say I'd feel out of place there. I'd like the benefits it provides, but it's money I can spend on more worthwile pursuits, and I just wouldn't fit in.
Besides, I'm gay; so I can't say the women are an attractive prospect for Greek life. I don't think I could handle being hit on by drunk women, since I have in the past and it was...uncomfortable. >_>
