Twitch specifies this is conditional: you’re allowed to discuss the political movement of that name, but not “attack or demean another individual or group of people on the basis of their background or religious belief.”
Zionist is a political term, it has nothing to do with one’s background or religious belief.
You’re entirely right.
But see if the political view is only held by members or a certain religious group (even if not all members of said religion accept said political thought), it’s easy to conflate it, so that you can ban anyone opposing said political thought based on “they’re discriminating against me because of my religion”.
Fuck twitch.
