It's OK if some people like different things than you.
French people liking to discuss politics online doesn't make them snobs. It just makes them people who like discussing politics online. And I know some very smart and politically involved Americans who are suckers for a cute dog video. Perhaps they'd be up for more poliltical discussion if every two years they were deluged with sly, dishonest, soul-suckingly stupid political advertisements. In France, with a population oif 63 million, presidential candidate spending is limited to 30 million dollars. My state has 1/10 the population of france, and the two leading candidates inthe last Senatorial election spent 85 billion -- and that's in an off year. So we Americans get exposed to a lot more unsolicited political communication than the French do.
But let's suppose that all things being equal, the French enjoy a good political argument online more than Americans do. So what?
I think resentment -- or even excessive concern -- over people who like different things than you is a sign of insecurity. When someone gets to the point where they insiste everyone join their side or be branded a fool or a snob, that's defeinitely someone who's seeking the safety of the herd.
