You seem to really like the word "bigot". Section 230 [1] is much more than "literally two sentences" and related to the current subject it clearly states that "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider." Hence the argument that Twitter removes user content because this is what publishers do doesn't apply: Twitter is not a publisher of this content. It does have some moderation rights, but the list of moderation reasons is limited and cannot be extended at will by Twitter policy; see III.A in [2].
