Only if that individual was also involved in the church's more unscrupulous activities. If he was simply a member of the rank and file people who were gulled into it, then no. My beef with the Church of Scientology is how it treats its members and its critics - if they cleaned up their act like the Free Zone practitioners of Scientology they'd just be another group of religious people who follow something that was made up.
BRTD, the type of bigotry you endorse is harmful to the movement against Scientology. It gives them the ability to legitimately claim their religion, and not their organization and its practices, is being discriminated against.
But like I said, if you give money to a Scientologist, you are indirectly funding the organization. I don't want a penny of mine eventually finding its way back to that cult. That's the reason why. As for my kid being taught by a Scientologist, I don't want my kid's head being filled with that garbage.
