Deleted my old account and made a new one with the rule of not joining any remotely political or country related sub. It's a good enough side for hobby subs which is why I went to Reddit in the first place. Much better experience.
Even the hobbyist subs will find a way to sneak in some "china bad", but it is at least greatly reduced most of the time. Definitely avoid any of the bigger umbrella communities (i.e don't join general gaming subs, join specific game subs. Same for most media)
I found the best strategy for reddit right now (besides not using it) is to go for tiny, less obvious subs where the average post has at most a double digit upvote count and a handful of comments. Anything bigger gets dangerous since it may get ranked higher in r/all
