I have friends all over the political spectrum. Recently a friend visited me from out of town that I've known since we were both 13. She supports Trump. My bf is a hard core liberal who voted for Biden. I'm an independent/libertarian who voted for Andrew Yang in the primary and voted third party in the general. We all had a nice meal together.
My Trump supporting friend said a few things neither my bf or I agreed with but we were polite. Later, we probably said stuff she didn't agree with, but she was polite.
None of us considers politics to be the most important thing in the world so once we realized we had disagreements, we stuck to other topics - of which there are many. Art, literature, history, science, technology, food, gardens, travel, pets... even world affairs but in a more generic sense without the partisan stuff.
The reality is that both Trump and Biden supporters (and those of us who tend to support third parties) have a large middle ground where we can find agreement.
None of us are fanatics. When I mentioned Trump's moral failings and idiotic tweets, my friend did not defend him. When I mentioned Biden's lapses due to age and pointed out the Dems had better candidates, my bf understood my viewpoint. Now, if someone is a fanatic - then we can't discuss this stuff at all. But people who can look at politics objectively can see the pros and cons of each candidate and party. JMHO. I am fine with people disagreeing with me. It's a free country.
