Well, I think that question is easy to answer. Often times people want to talk about what they feel happy about. I think that is just a part of being a social human. I do agree that such an action should be done without being rude or disrespectful. For this reason, I hate it when certain religious people go out onto the street screaming and yelling how people should repent or risk going to hell. As a Christian, that drives me nuts! lol. But again, to each his own.
