I used to feel the same way, but even the smaller ones are increasingly being co-opted by partisan screechers. Especially in the State/City/Town subreddits.

In the UK, at least one sub has adopted the "no politics" role. Political subs still exists, so there are places to vent political views too.

It already does on mobile. It is impossible to view subreddits unless you sign in, you only get a "preview"
