> Are you conforming/obeying when you believe the Earth is round? That the sky is blue?

No, I am incorporating multiple different lines of evidence from multiple sources, including my eyes, into a framework of knowledge that I am constantly challenging and questioning, and "the Earth is round" and "the sky is blue" have survived those challenges as good first approximations to the truth. Whereas "Jews control the world" has extremely flimsy evidence, strong counter-evidence, doesn't fit with my understanding of the world, and can be traced as a myth/meme to known bad-faith actors. Which, by the way, is all also true for "vaccines cause autism" and "the earth is flat".

Not everything is the same.
