People have been doing that tons - It's not being censored. Personally I assume this is due to western propaganda overstating the degree of censorship in china and rednote not being set up to moderate the large amounts of english content they're now getting.
So talk about the topics censored by American propaganda on there and the ones censored by Chinese propaganda elsewhere? It's so irrelevant as to be unworthy of a response.
You're free to start your own social media where you'll allow it, that's how free speech works, as long as the place where you're sharing your message is owned by private interests, the owner can censor you all they want.
That's because no one uses Lemmy. As soon as it appears on ADL/AIPAC radar it will go the way of Reddit with Zionist mods planted in the biggest groups.
And you'll still be free to create your own community, you can even create it on your own instance if you want. It's not perfect, but there's ways to work around issues like that on Lemmy.
