We really should be promoting education and discussion instead of hate. If you truly feel threatened and that your live or anthers life is truly in danger then that's a point where you would escalate the issue to either proper authorities or WC officials. Apparel is not life threatening. Hating someone because of their ignorance I think is just as bad as hating someone for their racial differences. Banning such things does not solve the underlying problem.

Promote education. Promote discussion. Promote progress.
