Do we really want to ask that question? We might not like the answer that some Ukrainians may give. Facebook was saying that "calls for violence on Russians" are okay given the context, full stop, then they clumsily backpedaled on the civilians issue and then only for threats they arbitrarily judge as "credible", which tells you how ridiculous the back-pedaling was. This is not going well for them.

Which country are the Russians in question citizens of?

Ordinary Russians are either invaders, or an unavoidable collateral damage - sad, but justified.
