Truth is not an echo chamber, accepting other people who aren't hurting anyone just by existing isn't an echo chamber, kindness isn't an echo chamber.

I don't need to consider "alternate beliefs" that are just lies. There's this idea that if I'm not constantly reading stuff by straight up Nazis, that I won't understand that they are Nazis. Not having to read nonsense as possible facts is one of the really cool things about having critical thinking skills.
