Each one, teach one!
Lesson one:
They need to understand that they are not the liberals, we are.
The proper name for them is “cosmo-totalitarian”, “cosmo-fascist” or “leftists.”
That’s why I _never_ use the term “liberal” for that group any more - they are not liberal by any definition, they are neo-Bolshevik anti-conservatives, supporting anything (like Islam) so long as it enhances their fight against conservatism.
Actually the proper term is Communists.
