Add a sensitive topics/trigger warning/political talk or whatever warning available as an option for channels.

Especially in Election Night in the USA, a lot of people want to talk about politics, and we all know that a few people don't like political talk. This also applies for other sensitive topics like channels about suicide, mental health, death of people, etc. Those topics are not necessarily NSFW. My suggestion is to add a warning option like the one in NSFW for topics like those, so that server owners can let people know what they're getting into.
