Also “Stop Killing Children” or “Demand a Ceasefire Now” aren’t “pro-Palestinian” messages, they’re anti-killing messages.
Just because the children being killed happen to be Palestinian doesn’t make that a pro-Palestinian message. It can be a general message that is applicable to whoever’s children happen to be getting killed right now.
If someone says “stop the attacks on civilians now”, how do you even know if they’re talking about Gaza, Ukraine or both?
