While not involved in any religious organization now, I can understand a few things.
Anyone that truly believes that their belief is the only way to escape an eternal damnation and that to save themselves also demands they try to save others, is not likely to be silent and not protest when they see society (in their opinion) going to hell in a handbasket.
Personally, I don't believe any religion has it all right, but I also don't believe that everything we see around us is a pure accident. I have doubts that any of them have even 75% right.
But I do understand people who believe trying to convince others of what they believe. It's just how far they go that is the question of right and wrong. I work with a man who is very sincere in his believes. He'll object to some language sometimes when used around him, but he does it calmly and politely still. He invites people to special events at his church regularly, but again he is polite not in your face about it. He regularly exhibits his faith in nonverbal and verbal means. But I've never heard him be rude, ugly, or condensing to anyone that didn't accept his belief. He can be persistant in a discussion, but if you walk away he doesn't follow you demanding you listen.
This is an example IMO of how believers should testify. I expect believers to campagne politically for candidates and laws that support not condemn their belief. That is their right. There'd be no point in believing something if you didn't object to things you thought were morally wrong.
