so I guess since I have replied to a few antivaxxers' treads, my feed is filled with antivaxxers. Even homeopathy and anti-chemotherapy posts are showing. it seems the algorithm is rage-bait focused (because it only seems to show the kind of posts that would trigger you, and not just regarding the topic in general, very one-sided as far as I can see) I guess I will stick to Japanese or English grammar topics from now on...
