For example, "we need to deport illegal immigrants" is a call for violence if you think about it, it's just violence through one of the acceptable channels - law enforcement.
The same is true of statements about war, whether it be in support of Ukraine, Israel, Palestine, etc. Maybe the violence is self-defense, but doesn't change the fact it is violence.
You don't see platforms removing these violent statements, because it's "acceptable" violence, but what violence acceptable is malleable. It changes in society over time, and it's different depending on who you ask.
