reply link: being open to other viewpoints doesn't mean automatic acceptance. I do listen and think. I'm not very likely to change my whole value system though, and I'm not about to trust news sources that have long histories of dishonesty. Remember that much of your news media couldn't even be honest about Trump feeding koi in Japan, editing the video to suggest that he rudely disrespected the ceremony. That news bubble is a bad one to be in.
The purpose of an open mind is to close on the truth, but that should be more like science than dogma. New information can change conclusions.
My value system is largely focused on the success of my descendants, including distant ones not yet born. They will prosper best if they have complete dominance for their country, culture, language, and religion. They are more likely to die off otherwise. To prosper they also must avoid the mistake of leftist government (socialism, communism, etc.) because that killed over 100 million people in the 20th century and it's still killing people today.
Answering a couple more points from your original comment here: I don't just enjoy watching Trump troll libs, but I do enjoy it. There is nothing wrong with a bit of fun. People on the right don't believe Fox anymore, and haven't for several years. There was an ownership and control change, with Roger Ailes dead and Rupert Murdoch mostly gone. Aside from two major commentary/interview shows, Fox is now leftist. Fox even hired Donna Brazile, the disgraced former head of the Democratic National Committee.
You mention that you despise the very thought of Trump because of the way he acts and how he doesn't care about the damage he does. OK, so what about that crime bill? I mean the one that put lots of black people in prison for crack. Joe Biden fought hard to pass it, Kamala Harris eagerly used it to put black people in prison with huge sentences, Hunter Biden was immune from it while smoking crack, and Donald Trump signed a prison reform law to stop the harm. How can you not despise the very thought of Biden because of the way he acts and how he doesn't care about the damage he does?
As you say, "I'd really like to understand how reasonable, ethical people could vote for someone I see as so despicable and dangerous." Yes, me too, but the other way. The 100 million are dead, and more are dying. The war in Iraq, supported by Biden, killed plenty. A few decades of life in prison is roughly equivalent to a death, and there were an awful lot of those. Perhaps you can explain why all these things are reasonable and ethical?
