If someone punches you in the face, and you ask them to stop, then they punch you in the face again, and again you ask them to stop, and then they punch you in the face yet again, and once again you ask them to stop, and again they punch you in the face, the question is not why don’t they stop when you’ve asked them to stop, it’s why are you still within arm’s reach of that person?
In other words, do not stand next to Bernie Sanders or Hillary Clinton because they will punch you in the face with taxes.
