Examples that come to mind:
- saying your favorite video game is Disco Elysium
- saying your favorite TV show is Star Trek DS9
The two rules are that:
- It has to be to do with a category that is socially acceptable to talk about with most people in a casual setting. So no politics or philosophy.
- Nothing too on the nose, ex, no “I love the music of the Red Army Choir” or something.
The term “fellow traveler” needs to make a comeback
Now, reminds me of hippies. I just blatantly say I’m a communist. Based on examples I think OP was aiming for humorous examples.
