Why on Earth would jokes have to "tolerate" race, religion and gender or anything else? The point of (some) jokes is to challenge anything and everything you deem to be a norm.
I'm starting to think that many tolerance-preaching people are the most intolerant bunch by far.
Well, my 2-cent is that you can laugth of everything but not with everybody... So defying the norms with Easter Eggs sent to the wild can be an issue. You have to know your audience to properly chose your level of impertinence.
I completely agree with the first sentence - however I would argue that normal, level-headed and sane person either laughs or just shrugs and moves on if that particular joke is not to their taste.
