Browse to r/worldnews... And that subreddit generally comes on frontpage.
I consume Reddit in generally the same way I consume Twitter - I completely ignore what's trending and only look at the people/subreddits that I've made an explicit choice to follow. Twitter's algorithm gives me more leakage than Reddit's, but I find it to be a tolerable amount.
Just browse r/popular or r/all any day. It gives you the most trending and upvoted posts on the whole site
Literally any post about ukraine will have redditors screaming for genocide against russia, upvoted to top. Same goes for China
Show me one single post about Ukraine where a top 3 voted comment is “screaming about genocide against Russia”. I will save you the time, don’t bother, because it doesn’t exist.
It exists in their fevered imagination.
I've seen posts that were calling for violence (usually directed against those directly involved, or leadership, which is natural given the circumstances), but I have not seen anyone (with significant upvotes) calling for genocide. If "any post about Ukraine" has this content, I'm sure it will be easy for you to link a handful of examples?
