Facebook now calls for violence against Russians. As of now it’s ok to post hate speech and violence on Facebook as long as it aimed at all Russian people. This an official Facebook policy.

"As a result of the Russian invasion of Ukraine we have temporarily made allowances for forms of political expression that would normally violate our rules like violent speech such as 'death to the Russian invaders.' We still won't allow credible calls for violence against Russian civilians," a Meta spokesperson said in a statement.”
