The strawman he wants to sell of course.
These people are fascists, their sole purpose is to lie about leftism because they know it's a more popular ideology than tax cuts for the rich and sneakily racist Southern Strategy inspired legislation.
They don't have ideologies of their own, and if they do, they're copying them from elsewhere.
Be careful they don't transmit the Amerobrain worms to you tho, internet makes stupidity to be extremely contagious.
