I vote completely progressive, but I agree there are demons on the left, just like on the right. The point at which common sense flies out the window and emotion becomes the driving force, it's extremism or cultism, not politics.
If you vote "completely" anything you are part of the problem. I vote for issues, not candidates or parties or political ideologies.
Politics are the modern day religions. You are either with the cult or you are the enemy. Really is a funny circle.
I think when whatever becomes a political movement (as it has to be one to attract awareness), it eventually brings in more bureaucracy to the point that "administrators" rule the movement.
