<p>I think what bbb360 says is very accurate. I mean, what you just said in your post is exactly the same. Frats regulate who comes to parties. They turn away people who look “sketchy” and try to maintain an even ratio of guys to girls. Discrimination.</p>
<p>I’m not saying it’s a big deal, but many frats do it, as you just said in your post. 
I don’t think bbb360 was trying to say anything other than that.</p>
