Don't paint all Republicans the same color. A couple examples regarding myself:
I am not anti labor union. I do believe unions sometimes go overboard with some of their demands, and I have had exchanges with union stewards that bordered on the ridiculous. It depends on the situation. If they are arguing for increased safety standards and protocols, I am likely to support them. If they are arguing for six hour work days for a job in a office setting (yes I've seen that), I am unlikely to support them.
I did not support Trump and the efforts of some of the Republican Party to overturn the election once I realized that there was mostly smoke and no major fires in the accusations regarding the election.
