Sorry, but I can understand disliking when it is made into an insult. But jokes hinge on touching an uncomfortable topic, making generalizations or making fun of someone, very often of the person who is making the joke even. Without that, jokes really aren't even jokes.
And nobody really should be treated specially to be shielded from something like that. Honestly I'd feel more insulted that somebody feels I can't "take it", that I have to be shielded than a joke itself.
