Really? Tell that to all the “liberal” regimes that enabled fascists when said liberals couldn’t keep working-class revolt in check… Weimar Germany literally did that to crush the “Spartacist” revolt after WW1.
There’s a saying amongst leftists - you can’t have a harvest of fascism without liberals loosening the ground for it first. Fascism is not some “aberration” of the classical liberal nation state and it never was.
