If you really were a rational thinker you would have to choose your side separately for every single issue

1. You should already do this for anything you care about? It really, really doesn’t take long for the important stuff. For everything else -
2. You don’t need to take a side on things you don’t understand. If you haven’t had the time to assess something… don’t share an opinion about it. It’s perfectly functional and rational for humans to specialize and leave problems for other humans to deal with. It is only social media that convinced people they should care about literally everything.
