For some reason the left needs to politicize everything. I used to frequent Board Game Geek. I think they generally had a left-leaning bent, but generally tolerant to nonconforming views with only flame war type posts getting deleted.

Right around 2020 this changed. They posted a manifesto on their front page proclaiming several "truths": blacks, trannies, women, etc. are oppressed. Their voices deserve to be featured and counter-posts that minimize "their truth" are invalid, etc. They started heavily censoring non-conforming posts and assumed a generally holier than thou attitude towards any dissent. The message became: "we know what is right and what is wrong; if you don't agree with us, you are immoral and either need to shut up so we don't have to listen to you or leave"

So now, if a "person of color" complains that a WWII game doesn't have a black character and you point out that it would be historically inaccurate, you're post will be deleted for being "dismissive" or "derailing".
