Just to be “that guy”, oriental isn’t a bad word in British English. It’s used very commonly in the names of Cantonese restaurants for example. It’s less commonly used to describe people, but if you did need to specify that the person was east-asian, it wouldn’t raise any eyebrows.
Not inherently, but I’ve been in communities where everyone is weirdly positive in the name of being “non-toxic” and it resulted in people generally not voicing dissenting opinions, which is pretty similar to an echo chamber.
I no longer frequent those places because it all felt a bit artificially happy like a kids TV show.
