If you want to be absolutely practical about that, not forcing politics onto everything allows you to be a lot easier to live for everyone around you, which is actually good for the cause. A lot of lefty people are super annoying to be around because they do that. In my experience, no one is willing to change their minds about controversial topics to someone who is constantly bringing them. Oppositely a lot of people will accept the views of someone they see as laid back, fun, socially acceptable and intelligent.
