Going back to tran rights like someone else just talked about...we are so far away from where we should be on some issues, that some people may need "echo chambers" (I'd much prefer they were called safe spaces since there's a key difference to me). They should not have to exist at all in an ideal world, but we're so far from that right now that they are necessary for some people, and there's nothing wrong with that type of "echo chamber" imo. You get the group/sheep think yes, but that is exactly what is needed in some cases such as that.
A safe space is not an echo chamber. People are not there to keep hearing the same opinion boucing from others with the exact same mindset, they're there to avoid being persecuted/harassed for some bigoted stupid reason. It's a far more serious issue than "liking games" so its kinda bothersome that both are being used as the same thing.
Where did you get the idea that I think people shouldn't be able to talk about these things and voice their own opinions? Everyone should feel free to do that. All I'm saying is that you can be aware that a game you like is divisive or that there are flaws, but sometimes you just want to enjoy it and not have to see or care about people shitting on the thing(s) you like because you're simply not in the mood.
Just used your example, not specifically saying you do it. If you're aware something like Fallout 76 is divisive and have a lot of flaws for instance, you should also be aware you cant just drop in a thread where people are discussing it and be upset that someone is going to be negative about it. You either put up with it and post your positives, or you just avoid the thread completely if it really upsets you that much that people dont like what you like.
