I've come up with an absolutely evil concept... the perfect way to protest the Vatican's position on homosexuality. Every single homosexual who gets married, has a commitment ceremony, or is joined in civil union should print and send one extra invitation to the event when they are preparing their regular ones. It should be addressed to the Pope himself and sent to the vatican just like any other invitation you'd send out to your friends. Surely the sight of hundreds of peaceful invitations to homosexual weddings is a powerful message to send to someone who opposes homosexuality?
