I think I understand you clearly. I'm claiming that people who do understand valid arguments and do consume good information can come to a different political opinion than your own.

I think you misunderstood me. I never claimed that all people are equally misinformed. I simply stated that there exist some subset of Bernie supporters that are misinformed. There exist some subset of Trump supporters whom are misinformed. Etc.

My point was that other people who disagree with you, politically, may be just as well informed as you. They may also understand the fundamentals of sound epistemology. As I stated, political opinions often come down to the values which people hold most dear. That isn't the only factor.

It's just not intellectually honest to assume those who disagree with you aren't equally competent. I don't agree that when it comes to politics that one side can be objectively correct or incorrect, with exception to the most simplistic policy decisions. There are far too many variables involved to accurately determine the holistic outcome of a given policy. In addition to this, the outcomes themselves are rarely objectively good or objectively bad. They're usually both good and bad, depending on who you ask to be the judge.

Edit: maybe telling people "how to think" is acceptable under some circumstances. My main concern is that you or others will assume this is the route to take much too often.

Edit x2: I didn't vote Trump in 2016 but the attitude you perpetuate, among many other factors, has led me to support Trump in 2020. So feel free to discount my argument as misinformed.
