There are two sides to this. My husband tells me that his first wife never laughed at anything except the misfortunes of others. For example, she'd sit stone-faced through a stand-up comedy routine but laugh herself silly if she saw somebody trip and fall in a hole. Seems rather sadistic to me, and I certainly don't want to be friends with a person like that. I say this even though I do get anything ranging from a giggle to a "rofl" watching a supermodel take a spill on the runway. This is just my own insecurity. I see myself as "flawed" but them as "perfect," and their splats show me they're not. I laugh because it makes me feel better about myself in comparison.

On the no sense of humor, though, one of MY pet peeves is saying something personal and mean-spirited, and then when the target is offended, coming at them with, "It was just a joke. Don't you have any sense of humor?" (If I hear one more "women belong in the kitchen" joke....) Fat jokes, ethnic stereotypes, and other insult humor would fall into this category. My family tended to make cracks that insinuated I was ugly or stupid, and expected me to laugh. I didn't. IMO this is a *form* of bullying, and as you say, bullies suck. I'm very sensitive to jokes that suggest a parent doesn't love or want his/her kid. When Bill Cosby told Malcolm Jamal Warner on The Cosby Show, "I brought you into this world, and I'll take you out," I was horrified. Where others heard a wisecrack, I heard a threat on a kid's life.

Jokes about body parts and biological functions strike me as a bit juvenile, and the laughs I get from them are limited. It wears thin, very quickly. I find it tiresome that half of the humor on the internet seems to rely on something resembling a private body part. After a while it isn't funny anymore. But it doesn't mean I have *no* sense of humor. What I find funny is simply different from that.
