Perhaps a bit late on the bandwagon, here, but I agree completely with the sentiment that no one should be ordered to have certain political or religious views. And that applies to way more than just submissives. The intellectual tyranny of people who demand obedience to a particular governmental, or, worse, religious creed is responsible for far too many conflicts - personal, or societal - to be taken seriously anymore. As some have said, even if you want to be with someone who agrees with you, it is simply impossible to order that person to agree with you. Agreement is won by countless conversations and an open mind, and may turn against you (that is, you may find that you agree with the person you are trying to convince just as easily as you may convince them, especially if you're really being open minded and not just pretending). More often than that, though, agreement exists before a relationship happens. Those of us who rate political and religious concurrence highly are apt not to get involved with people who we can't agree with.

My story: I am an atheist, but my submissive is a Baha'i, and I wouldn't dare try to tell her to believe otherwise. Despite being an atheist, I despise trying to convince people that atheism is "true" or "right." It's my belief, and other people have theirs, and the world is better for the variety of religions that exist (and would be better still if more people appreciated that variety, instead of fearing it). A relationship is the same way: my relationship is better because my sub and I believe different things, and our conversations are richer because we don't always agree. While we don't have so many political differences, I think the same could be said about those who do.

Personally, what I can't stand, and what I feel it is fair to demand of someone I love, is a certain degree of awareness and education (as in: "read this"). I would never try to convince a Christian, for example, that God does not exist, but I would try to, say, make one read the Bible if she had not. Different beliefs make the world richer, ignorance makes it poorer.
