From the top of my head - direct praises of hamas, sharing of the paratrooper meme, sharing of the star of david beheading babies meme and generally a lot of people direct or indirect calling that the Israeli deserved it. There are a lot of Mia Khalifas out there.
Since october 7th there I have observed (probably because a lot of people I follow on twitter are jewish, so they kinda amplify the nasty content) serious rise in "gas the jews" types of antisemithism on twitter.
Some of it edgelording of course, but a lot of the content there has serious bite.
