Why are liberal hangouts infested with White People? Aren't they multiculturalists?

Buddy, you have no idea. I attend a liberal arts college and I am in the thick of it. Everywhere you turn, hipsters, rich kids dressing poor, Apple computers, a cafe dubbed "Hard Times" (can't be to hard, as everyone in there sits around on their $1000 Apple computers). In reality though, these same liberals are usually scared to mingle with people of different backgrounds be it racially, religious, etc. They are truly hypocrites.
