does a minority stand a chance?

Hey guys, hoping not to start any drama with this thread but it might happen anyways. I'm an incoming freshman and I was wondering which middle tier frats seem to be pretty open to minorities. There are only so many rush events and I don't wanna spend too much time somewhere where I might be at a disadvantage.

Along the same lines, which mid tier frats don't seem very open to minorities and/or are almost entirely white? Thanks.
