Before everyone gets out of hand on this topic of being all Jewish, if you read the mission statement of Alpha Epsilon Pi,
http://www.alphaepsilonpi.org/information/index.html, that's what they are...the Jewish fraternity of North America. That being said, I'm pasting the last paragraph here, which I think will help others see what AEPi's NATIONAL stance is on this...
"Therefore, our basic purpose is to provide the opportunity for a Jewish man to be able to join a Jewish organization whose purpose is not specifically religious, but rather social and cultural in nature. Alpha Epsilon Pi is a Jewish fraternity, though non-discriminatory and open to all who are willing to espouse its purpose and values."
I think it's fair.
