Trump is a convicted felon, rapist and fraud, who knows nothing about governing and doesn't care to learn.
This is why he is dangerous.
We require governance not incompetence and lies. What you are arguing is that it's okay to have a pathological liar and sociopath run our country because it's all set up to run itself. But you are wrong.
It's set up for good people make things better for all of us. When bad people take over and break all the rules bad things happen to all of us. I put this in the simplest terms so you can understand it.
