I think it's human nature to want roses without thorns. That is, to want things to be all upside and no downside. That tendency in us easily motives us to deny reality. There are none of us above being fooled by it. We're always at risk of denying reality. Every one of us.
I don't see how a Senate trial can fail to further divide the nation. Or, for that matter, any action taken against Trump. Giving him a parking ticket right now would be met with shock and disbelief. Anything more and the outrage would be a storm.
On the other hand, do we want our democracy? How long do we expect to keep it after revealing there is no punishment for trying to overthrow it?
I wonder how many fires would be put out if fire fighters were in the habit of backing down whenever going forward brought with it significant risks? How many lives would be saved if doctors only prescribed medications and performed surgical procedures with no risks? Do many such things even exist?
