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.
@RickiTarr No I say you duty to consider alternate beliefs so you can be sure that they are lies and that what you believe is actually true.
That is, you need to do that if you want to have a higher level of confidence in what you believe, especially in what other people have convinced you of.
There's no alternative to the scientific method.
