IANAL, but IIRC in such circumstances, the powers-that-be don't get to discriminate among words, especially ever since SCOTUS discovered the "right of accommodation" somewhere in the Constitution. So, banning all clothing with any words whatsoever would likely be okay. But banning religious/political speech in the form of words on clothing? There be dragons.I don't know about that. I've seen businesses get away with banning revealing clothing, clothing with words, even clothing of certain colors. I support his right to wear that shirt, but I also support the rights of a private business to set the rules for their own establishment. If we are to support freedom, we must support freedom for all.
