when did this become a twitter cliche? can you read the room?
It's usually a call to moderate your behaviour or internet spoutings no?
"Read the room John - nobody wants to hear about why Ragga Ragga Ragga 12 is an amazing album in the middle of a twitter storm about Epstein".
I think there are two sides to it - one is community and one is hegemony.
Community is good (but has its downsides). Shared values, solidarity all that stuff. Occasionally someone behaves like a prick and you have words and they might go off in a huff but they will usually come back with suitable encouragement and we've all done it.
Hegemony is bad (but has its upsides). Trying to impose a uniform set of beliefs and values. Cutting out the degenerates and nonconformists. But at the same time we have no need to tolerate racist pricks.
You get this a lot when people die. Social media being based on engagement/enragement - someone ALWAYS comes out with something insensitive about the deceased. And this was especially prevalent (and mainly excellent) when Thatcher died. There was a real attempt to do "both sides" of her legacy and present people who were glad she was dead as awful. But it didn't seem to work.
