We’re not there yet, but we are well on the way to becoming a third world country politically. Trump is a politician fit for a third world country. But we also had members of Congress recently abandon their institutional roles and get themselves arrested at protests. I think even Sanders had more dignity than that.
Like many thousands of people, Sanders was arrested at civil rights protests. I don't like Sanders, at all, but he certainly gained "dignity points" for that. The logic you're using to flatten things down isn't working; it's equating things that can't reasonably be equated.
