Republican grievances have a lot of overlap with Democrat grievances, and even on the high-visibility topics where they don't, Republican grievances are still mostly based on real issues. It's many of their policies and ideologies that are immoral or un-American, not (most of) their grievances. You may feel like you're in the minority, but I actually think people generally believe this, but won't admit it without overwhelming caveats, because of aforementioned policies/ideologies.
