I see a problem with that approach and it has nothing to do with politics. If you follow only the people you add, that limits your feed to things you chose to read, explicitly. So you'll never discover new things. Let us say, I want to follow a broad selection of everything, but don't want kitten (or don't want politics, but kitten is neutral...). There is not way to do that. We would need a way to curate the feeds from kitten, but there isn't one.
