If your parents feel “betrayed” because your wrote about their political opinions, it says a lot about the foundation of those opinions.
A confident person, with well-reasoned political ideals will not feel any harm if someone else writes honestly about them.
However, if they get upset when a light is shone on their ideas, it reads like insecurity.
I love your point about understanding that you don’t really matter. Which is liberating for a creator.
I wish more people understood how little their opinions matter. We might stop fighting and unite.
