I read "We hate anyone who doesn't agree with us."
Said out loud: "We hate bigots and fascists."
Unsaid but implied in many interactions: "Anyone who doesn't agree with us is a bigot or a fascist."
Combine: "We hate bigots and fascists, by which we mean anyone who doesn't agree with us."
Simplify: "We hate anyone who doesn't agree with us."
You used "we". Who is "we"? The rest of the discussion implies that "we" means "we Hexbear users".
So here's a better question: how can a White, cisgender, ~~cissexual~~ hererosexual man politically to the right of Bernie Sanders disagree with you without being a bigot or a fascist?
