I may vehemently disagree with someone about their approach to others or views of supremacy or similar, but if someone attempts to organise an effort to blanket censor those people, I almost feel compelled to stand with the person I have no alignment with on the sole basis of the principle of freedom of expression.

If you suppress speech, you force it into echo chambers which always result in more radicalised views. By being a censor, you directly contribute to radicalisation by disrupting discourse.
