>we won't accept other[s] not accepting it

I think that's right. Paraphrasing Popper: "In order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance". It's not about being right or wrong, it's about how people should treat each other, even if they dislike how the other one acts.

In order to maintain a tolerant society, you must not tolerate intolerant actions. It does not require suppression of intolerant opinions.

I don't know how I would go about the specifics of implementing it, to be honest. Let's suppose we suppress the actions, not the opinions. Is allowing someone to express their opinion an action? Is operating a platform (like Twitter), and letting intolerant opinions proliferate there, an action?
