You’re highly unlikely to date someone for a extended period of time and then suddenly learn they actually heavily Catholic or part of the Klan. Generally if you share some basic general interest you share broader interests like politics just because they are related. If I met a girl/guy fishing I shouldn’t be surprised to see a rebel flag on the second date. If you date someone for 3-6 months then suddenly you notice all the ww2 natzi medals, and marble busts of elon musk in his master bed room then you are also the hot mess. Most of the things you’re going to have disagreements about politically are minor and trivial.
