As an American I’m about 7 years past having a sane conversation with half of them as well. Recently had an experience where I “convinced” family members to support a far more sensible very left leaning agenda (for the us).
It required more skill at arguing that it did facts. And started with a hilarious level of common ground. Asking if the CEO killing was justified considering what he was responsible for.
My head hurt through the entire process and I doubt it made any lasting impact.
But, my experience is that most are so far gone down the insanity rabbit hole, it’s like reading sections of 1984.
I mean yes. The phrase that followed me through large multimillion dollar sales campaigns is that “people buy from people (they like.)” You can be the best, but if they don’t like who they’re dealing with it doesn’t matter. This is more true on these larger items where you will have high touch after the sale.
