What I have noiced-
When liberals don't like the facts that you are speaking, they give you negative label; something -ist or -phobe. Doing so, in their minds, makes you a lesser person who is unworthy of their attention, and they are now justified in dismissinig anything you say. In their minds, they have won the argument. Then they shout you down to keep your speech from being heard by others. Whether in person or on social(ist) media... they disagree, label you an -ist or -phobe, then shut you down. They can't have people offering alternate ideas, nor can they allow people to think for themselves.
