You should also ask "Why isn't it acceptable to say that what Hamas did to Israel on 10/7/2023 was evil?"

Why is it so easy to see the pains of Gazans without sparing a tear for the pains and losses experienced by the Israelis?

You can shed rivers of tears for Hamas without a drop of tear in sympathy for the Israelis.
When you're ready to empathize with either side, I'll take you serious. Selective empathy is fuelling the crisis.
