This is true, I know for a fact there are people who I have on my flist who are of completely opposing political standpoints to me, and who do not agree with a lot of my ideology. But I welcome them here because the only way to learn anything is through questions. People who don't agree with what I have to say make me question what I've said, make me either back it up or explore other options.

But then... I consider myself pretty web savvy and as such deliberately encourage other opinions wherever and whatever I post. It would be incredibly easy to get stuck into a niche and never see any other points of view.
