Such behavior usually belies an underlying insecurity in one's own convictions ("Well, if the other side has a demon, then it is ok to go along with this shit to avoid something even worse").
We all know your vote has been predetermined (democrat), and there is literally NOTHING that could possibly happen that could change your vote. A rational response to your attacks will be guaranteed to fall on deaf ears. You do not want to hear that most home loans are insured by Fanni and Freddie. You do not want to hear that just because a person took a loan out within the existing banking system, it does not mean that this same person is not allowed to point out improprioties within that system and propose change.
You should sit back sometime and ask yourself why you feel the need to demonize, but of course denial will be your course of action.
