Aw c'mon bud, don't beat me up over "tribalism" versus "tribal values". It's not ambiguous, because you instantly knew that being an anti-vaxxer is synonymous with a republican position. Also, just want to make sure you're not having an absolutes argument? Because we're just talking in general. There are always plenty of exceptions.
Anyway, the goal with my thought process is often to leave room for people that feel disenfranchised. I don't want people to feel cornered and I want them to feel like they have somewhere to go. For example, I often try to separate republicanism from conservatism, so that someone that was a republican prior to 2016, and they were a republican because they held conservative values...I make that distinction so that they don't feel forced to be a republican and know that it's okay to be a conservative. It's bad to lump them together, because if you do that, then you're pushing conservatives into the republican party and you're harming your own interests, because democrats and conservatives can work together, but democrats and republicans cannot work together.
