I miss a lot of what goes on here because I deliberately avoid quite a few posts based on subject matter for my own wellbeing, so I don't know what you're referring to specifically.
I do know that you can get moderated for responding "LOL" too often, which is certainly censoring opinions, as it's often used as shorthand to say "this is laughable/absurd".
It is ridiculous and wrong to censor someone for saying "I see you. I see what you're saying here and I think it's BS, but since I KNOW that you're unwilling/unable to see things from another perspective, I'm not going to waste my time or energy trying to argue with you or give you facts that you will not believe under any circumstances. But I do see your BS."
It's ridiculous and petty and very telling. For me, it's not worth getting into an uproar about. But the hypocrisy of those crying 'snowflake' is definitely LOL-worthy!
