I don't think the pro-Israel position is "mythical", but I can imagine that if you go out of your way to stay in spaces that affirm your own beliefs it probably does feel that way.
I didn't say that the pro-Israel position is mythical. I said that no one became pro-Israel because people are saying that Israel is committing genocide. They were pro-Israel to start and just use that as a rhetorical device to try to get people to stop saying Israel is committing genocide.
