Jokes are FINE. But sometimes they make things get out of hand. Humor is not something onesided. My opinion on what is funny might be different than anybody else on this whole site. And I have to say that sometimes it seems to me that jokes are beeing used to insult people with different opinions. Humor is such a strong way of expression. In the end it might be seen as it all comes down to ethitcs. Sometimes it might help to think throug if one has had enough empathy with other people and their opinions. Excuse me for beeing serious. That's the way MY mind works. But PLEASE do tell jokes. 

Here's a SONG for ya':
"The world is full of Kings and Queens who blind your eyes and steal your dreams. It's HEAVEN and HELL. Oh well. Fool, Fool! Look for the Answer!" Ronnie James Dio(Black Sabbath) Heaven And Hell(1980)
