Respect is saying "We disagree on topic X, but I acknowledge that you are intelligent, you have thought about X in detail, and you have constructed sophisticated arguments which took me some thought to refute. For these reasons, even though we disagree, I consider you a worthwhile conversation-partner."

Those are all things I'd have to discover about you. There are some here I consider worthwhile conversation partners because I recognize their usernames and have formed opinions of them.

I don't expect respect from people who don't know me, and I don't even expect it from those that do know me. I am not due respect from anyone, I have to earn it, by their lights.
