I make jokes about every one, that is why i am a man with a lot of enemies.
First thing that came to mind for me when i saw the title (mainly because the title read "I make jokes about every one and that's why . . .)
The main reason is because not every one has the same sense of humor. Do you find the blue collar comedy tour funny? Do you find Kat Williams Funny? How about Lisa Lamponeli? Mitch Hedberg? Demetri Martin? Dane Cook? Mr. Bean? Slapstick? Fart Jokes? Dark Humor?
If you can't say yes to everything, then there are things you can't laugh at. So the things you do laugh at "making jokes about everything/every one" doesn't encompass everything and every one.
Hell i fall under the belief that if you can't laugh at it then it has beaten you. I laugh at the "amputation" i had, i lost a body part but i still laugh. I make jokes about family issues, i laugh about friends and exes, about the war i will have to fight in, the things i have lived through in life, but that is my way to keep myself swimming in a current of shit that wishes to drag us all down.
Some people don't do that. Some people don't believe humor is the answer. Some people don't laugh at awkward situations. Some people sense pity and not humor in irony, in slap stick, in dark comedy. Hell, there is a reason most dark comedies are indy.
Did you laugh when Brad Pitt was shot in the head during Burn After Reading? I did, i know people that didn't. But these are trivial.
Now imagine you tell a holocaust joke, a lot of us have and a lot of us will, i bet you and your friends laugh. Think a survivor would? Tell that joke around some one who takes offense and you made yourself an "enemy". Every joke (most of the good ones atleast) are built around the shock factor. They push the limit. Its why a man who isn't racist still laughs at a racist joke. Why we find humor in stereotypes, and when comedians point out some dirty little secret every one has. It shocks you and makes you laugh. Hell one of my favorite jokes to tell is funny because of the reaction people give, not from hearing the joke.
But when you make everything trivial by joking about it you can offend people, or mock what they truly believe in or stand against.
You may not have prejudice, but if some one perceives that you do then you are no better than a racist. Because in that person's eyes thats what you are. Go ahead tell a black joke to a stranger on the street. Just the joke. See what they see you as. You could be married to an african american. Tell that joke and you are seen as a racist, so in his eyes you are a racist. Perception is everything.
