Bear with me here for a moment.

There are acceptable "censorships" and censorships which you should stand up against - because sooner or later the latter will bite you in the ass too.

So, on the top of the acceptable so called "censorship" - it's basically platforms and media moderating content published there. It is better when they have their own criteria, more conservative than the legal framework, in order to keep content in line with their goals/agendas.

Under this fall, e. g., news portals moderating comments under their articles and hand-picking their staff and guest authors who are being published on it.

It also applies to fringe portals; Breitbart has a full authority to censor me if I go nuts and decide to comment there.

I will mention here free market for the first time. Free market provides and private media (unlike one owned by the state) are not expected to be unbiased. There are obviously issues with that too, but it's less of a problem than not having them like that.

So, you get it. You run a platform where you publish your content and you want to try and benefit from your consumers' engagement. Please, by all means, do moderate it. I don't care where you are on the political or social spectrum - moderate the hell out of it.
