Liberal is too mild an Epithet. Marxist? Stalinist? Facist? That fits.
Liberal sounds like Woody Allen talking about petting on the first date. ‘Socialist’ is closer but not really describing the evil that exists in America today.
I would suggest that ‘Liberal’. as a word, is easily on par with the others and has racked up as much death, disease, destruction and suffering under it’s manner as straight up Marxism ever did. And as such deserves to be reviled along side them.
