Yeah in my experience it's largely where you go.

Leftist spaces obv have a lot more Palestinian independence discussion.

There are lots of moderate spaces that allow open discourse that still slant toward the anti-genocide part of the equation.

Then you have places like worldnews that heavily moderate out any pro-Palestine discussion and allow for heavy astroturfing. This is kind of a big one because it's one of the more popular places to get non-US news. So if you didn't know how it was being moderated, you might just assume that reddit is just randomly super bloodthirsty or something.
