At the end of the day they have been conditioned to hate liberals/Democrats, and anyone that gives them hell, they love.
We have seen NO evidence that any negative character trait was sufficient for them not to support Trump.
We have seen NO evidence that being unable to advance any real Republican agenda (for which there isn't any), has turned them off either.
Indeed, what else is there that drives that blind loyalty?
You can see it indirectly, where they claim they are the real victims...victims of the PC police. Victims of people who tell them they are racists. People who ridicule their inability to make a lick of sense. For being ignorant on nearly every topic that they preach about. For living hundreds of miles from any border, but being so mad at immigrants. Etc.
They are mad at being ostracized from the modern world that is leaving them behind, and Trump is a cudgel to hit back. Not too long ago, these types were willing to kill other Americans in an effort to keep human slaves. I mean, maybe this is progress.
This is about as dishonest as it gets. Let me address each "point":
1. I've never been conditioned to hate liberals and/or Democrats. I've actually voted for a handful of Democrats in my life. What I vehemently oppose is the far left, which is where the Democrat party has moved.
2. Trump has negative traits, particularly a thin skin and inability to shut up when needed but, in the essentials, he is right. A POTUS needs to put the US first and then worry about the rest. That is what Trump does. That it enrages the left says more about them than Trump.
3. Trump has made strides on jobs, trade deals, making our allies more accountable, etc. The lack of progress on immigration results from him being up against powerful forces on each side which want the status quo.
4. Oh where to start? Yes, the PC police are pernicious. They are like all the little functionaries you'd find in every totalitarian government, just glad to have something to do and gratified that it involves curtailing some activity they decide should be curtailed. Racists? Now, that is a standard go to response from people without ideas. If you think that all conservatives and/or Trump supporters are racists then how could one have any discussion? You can't, which is what the left counts on. Mad at immigrants? Hmmm..is that illegal immigrants, all immigrants or just the brown ones you like to rail about? Personally, I like immigrants. My Mom is a first generation immigrant. I also married one. I've known plenty of them, too. So, no, I'm not mad at immigrants. Hell, I'm not even mad at illegal immigrants for the most part, only at the people who want to perpetuate a system where they continue to come here and get protected after doing so.
5. Ostracized from the modern world? Oh, you mean disagreeing with liberals. If that's what you mean, then I'll gladly accept such ostracization. Ah, now we're really in the weeds. Let me get this straight; being a conservative or Trump supporter makes you a Confederate or, more specifically, a would be slave owner. Have I got that right? If so, then this is just further demonstration of the left's need to attack their opponents' characters because they can't win on issues. You'd think you guys would have drained that well dry by now but it seems not.
