Hard to tell in hte case of Slovakia. The government, the extreme right (pretty much nazi) members of parliament and some other parties jumped on the populist wave of anti immigration rhetoric. I want to believe majority of the people are good and would help. Unfortunately the mental setup is that people envy also war ("immigrants get support for free, we have to work all day and pay mortgages...") I would guess it's similar in Poland and other countries. Also important fact in this whole game is that we literally have like a dozen of immigrants in Slovakia, so really no threat at all. More dangerous is the hate that's currently spreading across the nation.
