Don't actually do this, but if you search "trans" on Twitter and sort by "latest", you get about half transphobia.
About 50% of the posts you see with the word "trans" in them, on Twitter, are so transphobic that they'd get your account basically instantly blocked by most of fedi.
If you search "trans" on Mastodon.social (which is sort of the worst case scenario here), you get exclusively positive or neutral posts.
