This is 100% true. Even worse than those losers are the people who argue with you in order to "keep an open mind", and then who say "your opinion is valid" even though they would never in a million years believe it the same way that you believe it.

Both types of people are awful. I would rather encounter someone who looks at me the same way they would look at a really fascinating bug, asking questions and challenging my beliefs just to see how I'll react and just to try and figure out how I "managed to develop such wrong beliefs." That's the kind of person I want to have all of my arguments with.
