What kind of person responds to someone’s joy with an agenda? I don’t even care if you’re right or wrong: that’s dehumanizing (and last I heard, most people on both ends of the political spectrum are generally opposed to dehumanization). You’ve heard of the Culture of Death, which teaches people to sneer in disgust at the good, the true, and the beautiful. What we have here is its sad sack cousin, the Culture of Blechh, which teaches people to turn every occasion, whether happy or sad, into a basin to catch the Very Important Message they perpetually disgorge.
