Most of what I hear from sources like Voice of the Martyrs is that most of the violence against Christians in Europe is extremist Muslims, often labeled as "Asian" immigrants or refugees if the story gets any coverage. Those extremists don't like anyone who isn't an extremist, so they hit Christians, non-extremist Muslims, whites, their own children and wives, ect, ect. I know there are anarchist/antifa groups that are growing, but what I see is that they are rioting and doing group attacks.
That's just what I'm seeing though. What news one gets today always depends on where one is looking.
