While I applaud your attitude, it's often shortsighted. The people with evil or impractical ideologies will never stay quiet, and if they get enough followers, they'll start causing real problems for people like you. There's power in numbers and we all have to play the same game.

And if you feel the opposing ideology is wrong, don't you have a moral obligation to inform others of the alternatives? Making your point and convincing people with real, practical results is far from becoming an intolerant preacher or forcibly controlling others' behavior. But that kind of people are often what we are up against, and we shouldn't forget that.
