Go tune into reactionary talk radio for a taste. Really listen to what they're saying and just let it wash over you. I'll do this occasionally on long drives by myself when I'm out of range of familiar radio stations.

The problem isn't so much differing values in terms of specific policies, but rather a deep chasm of anti-intellectualism that makes them mistrust anyone but their ingroup partisan preachers. Even if you are coming from a place of mostly agreement about some issue, and appealing to values they purportedly have, the minute you start deviating from anything the preachers have said you've immediately put yourself into the "other" camp where their only conclusion is that you "don't understand" or are even trying to trick them.

Those partisan preachers had at least been owned by US business interests, preaching policies that hurt individuals while helping entrenched corporate interests (eg the decades of shipping industry to China). But at this point it seems they've been bought by foreign interests hence the new trend of supporting the wholly destructive policies of trumpism.
