Confirming your contempt for Trump and his supporters, you validated my original response to your comment.

I checked, by the end of February, according to Gallup, among registered voters, 43% approved and 53% disapproved Donald Trump’s job as president. Among Republicans, approval rating is 90%.

When Donald Trump started his presidential campaign, I called him the leader of the deceived: https://www.henrykkowalczyk.com/immigration/the-leader-of-the-deceived/. Hence, the Trump is not the problem, so many so deeply misinformed Americans are. Sadly, on the opposite side similarly deeply misinformed gathered behind Bernie Sanders.

In my guesstimate, majority of Americans are so deeply misinformed on at least one major political issue that a well-informed person can “admit to harboring contempt.”

We have two options. As you mentioned, blood can lubricate the change; those capable to kill more of their opponents will win. Or, we can just talk, and those having better arguments will win. What is your preference?
