There have been a number of studies around the world, plus some real world examples (Utah gubernatorial 2020) where showing your opponents in a sympathetic light can make a big difference in reductions in political polarization.
It’s especially effective when signaled by the “elite”: https://journals.sagepub.com/doi/full/10.1177/00323217241300...
Edit: I hear plenty of stories of people abandoning family members over a difference of political opinion. My MIL won’t talk to a niece of hers after the niece made the same decision. I won’t go so far as to say that’s never warranted, but it seems these days that it’s happening a lot more.
To me, this implies we’re losing acceptability of political “others”.
Turn on the largest mainstream media "news" channel, and you'll hear nothing but mindless hate for 20 hours a day, without consideration for what actual news is occurring.
So up until this point it was perfectly acceptable? Or is this only an issue when the wrong side does it in a fairly moderate way (since the other side regularly and openly embraces and encourages political violence).
However, some people support and vote for, a president who has told his supporters to perform acts of violence against those whose speech he disagrees with, clearly a portion of the population doesn't mind.
I think this is being seriously accelerated by Trump. Why should I treat those I disagree with with dignity and respect when the President (who theoretically is a leader for all Americans, not just the people who voted for him) says things like this?
"And when you look at the agitator, you look at the scum that speaks so badly of our country, the American flag burnings all over the place, that’s the left. That’s not the right."
When Trump and Vance start setting a positive example for others to follow, maybe I'll rethink my position, but leadership and accountability start at the top.
All you’re doing is ensuring the strength of their beliefs.
Edit: You don’t have to like someone to not actively attack them at every opportunity, even if what they believe is reprehensible to you.
