Saying stupid shit is how they (in their minds) own the Libs. The stupider the better.
The whole idea is to trot out nonsense that would take 5-10 times as long to address, if one had the stomach for educating assholes. Assholes who actually know the truth, but don't care, and in their hatred of libs, only want to lie us into submission.
Idiotic lying is gaslighting and hate-speech. They know many in their company are unstable and they hope to incite violence.
