But the act of wearing a special gay-activist sash while receiving communion is, ipso facto, an act of defiance of the Church and an insult to Christ. Also, as the old Anglican Book of Common Prayer used to warn, like the Tridentine Mass, anyone who receives Communion unworthily is "eating and drinking damnation unto himself."
It's the same principle as St. Patrick's Day parades. No one is going to stop homosexuals from marching with everyone else, as long as they don't call attention to themselves with political statements or special costumes.
