It is not a valid argument because it is made in ignorance.

All you need to do is educate them on what the phrase means.

They can either accept the truth and change their tune, or continue their stupidity.

Liberals like to think themselves more educated and enlightened.

That WAS true of classical liberals.

That is not true of socialists masquerading as liberals.

Hit them where it hurts - their assumed intellectual superiority.
