Let me see if I can break this down for you....
1. Mainstream American society prefers outgoing and sociable people over quiet and introverted loners.
2. American universities are mainstream.
3. As per the statements of members of this forum, frats play a prominent role in American universities.
4. Is it really that shocking to think that a prominant group in a very mainstream American atmosphere would be encouraged to do something that mainstream America likes? Namely, be sociable and outgoing.
Now let me break the compliments down for you.
1. I am an introvert and a loner.
2. US society is naturally suspicious of introverts and loners.
3. While I am happy with myself, I admit that I would like to be in a position that is more embraced by mainstream America.
4. Even though I do not wish I were extraverted and outgoing like most frats encourage their members to be, I would like to be as socially accepted a frats are.
Another "compliment breakdown" for you:
* Even though I know that I personally would never fit in to a college fraternity, I know that there is a great deal of brotherly love in them, and I think that is beautiful. A person in my position, a loner and introvert, is not as likely to receive that type of brotherly love from other men, and therefore I am envious of men in frats to a certain extent. (I've tried to emphasize that I myself do not get off sexually on the idea of homoerotic innuendo in frats. I'm interested in it from a sociological perspective.)
* People often find interesting the things that are unlike themselves. I can't think of a group of people more unlike me than white, suburan, college boys in a fraternity. I grew up in a black neighborhood in the inner city, am a loner and introvert. (I know there are black fraternities; they are not all white. But most citizens of the US are white, and white is what is mainstream. Black colleges and black frats are not mainstream.)
Your thinking is very linear. You need to try to be a little more interpretive and lyrical when you approach what I write. The world is a complex place, and I write about complex topics. Frats, and my perspective on frats, are complex. On one hand, I think the brotherly love within them is beautiful; on the other hand, I think that conformity it teaches is potentially dangerous. Life and the world is complex. If you can't deal with that fact it's not my fault.
