That is not a thing that has ever happened. Conservatives are completely fine with dehumanising their enemies and criticise toxic discourse at the same time. Contradiction is baked into the ideology, and they thrive on it, because there is one set of rules for the in-group and another for the out-group.

The main idea of their hateful rhetoric is dehumanizing and demonizing anyone who isn’t a US-born white male that agrees with them. If you’re anything else they hate you and would prefer you not be alive.
