Can we please stop giving liberals an out for willingly participating in and supporting fascist policies? They are not "playing into" the hands of anyone; they are doing it with great intention.
At minimum, liberals support nationalist policies and capitalist policies. Both of these policy categories support fascism.
You cannot "unintentionally" do something that supports fascism while intentionally doing the thing that people are openly criticising you for doing -because- it supports fascist shit.
Make them equally as responsible as the right-wing. They do not get to escape this.
