It's just not worth it. Publish or tweet something if you have something to say and want to reach a lot of people. Talking to ONE person and risking your relationship has a lousy cost/benefit ratio.
I generally keep people's political opinions at arms length, as some relationships are worth the pain or lack of depth. But it has caused unforseen pain at times, and hurts when relations from different spheres interact negatively.
F.ex. one of my most altruistic and charitable friends is a Trump supporter
She's run a Christmas time charity for 10 years, solely out of the goodness of her heart, to ensure that families in our community who are struggling get what they need for a happier holiday in tough times.
It's a non-trivial 6 months of work, between making prizes for donation-driving lotteries, attending events and promoting, and then finding the most cost-effective deals for the families.
So I choose to say "She's a better person than most I know, in some ways, and disagrees with me in others. Worth friendship."
What’s the endgame to this approach? Seems to me, folks with genocidal thoughts and feelings would find more positive reinforcement amongst themselves and less negative reinforcement everywhere else. Not great for the “genocide is bad” theory.
It's hard to imagine isolating them from counter points is going to mitigate their position.
Like we all know a guy who we can't keep around because he keeps saying unhinged stuff, or creeps on any women, or whatever it is he does that ruins it for everyone else.
So I think it's more nuanced than just refusing to cut off heinous viewpoints. It's also how this person injects this view in your existing friend ecosystem.
But the premise here is these people have these beliefs and are working to make them legal. The idea isn’t that these people want to kill Jews, it’s that they want to make killing Jews the right thing to do.
Then, it becomes your problem. Particularly so if you are Jewish, but even if you are not.
This of course extrapolates to less extreme examples.
When challenging such beliefs I find some are hyperbole or a side effect of group-think. Rarely are they genuine, but when they are it's the most worrying. And that's usually when I stop engaging that line of thought.
so I guess I agree to some degree
