I don’t think there’s anything legal that you can do on this case. You’d have to limit all religious efforts on a campus to make this work.
Now, if you really wanted to take the ‘brothers’ down a notch....just get every guy on a campus with a sense of humor to don a Washington Redskins “burka”, and walk in public with it, and attend classes wearing it. Use every bit of American-style humor to take the ‘brothers’ down. The legal idiots can’t ban humor, and they’d look stupid attempting to stand against humor.

IMHO the easiest avenue to take is the fact that Islam is not a religion. It is a government. When all is taken into account it looks and smells like a government, and very unlike a religion.
