The ideal sense of humor

So, Rachael and I once again had an arguement based on her feeling like she's caring for me, and me feeling like she's treating me like shit. The arguments go like this:
1) She says she cares for me 2) I let her know that I don't feel like she cares for me when she disrespects me 3) She refutes my claim, asking for an example

In this example, I cite a joke Rachael told earlier in the day, where I saw a bee and Rachael said "I wish that bee would sting your dick and make it bigger." I use it to help explain how she disrespects me.

Rachael: What do I do that's offensive?
Me: For instance, earlier, you said the thing about the bee
Rachael: That was a joke, but some how you think I'm evil for it
Me: You don't see how it may be offensive?
Rachael: Everyone else thinks I'm funny, but you don't get it. People love my sense of humor.
Me: By that logic, you feel like you can go anywhere any everyone will say you have a great sense of humor.
Rachael: Well, if you see an orange, and you call it a banana, that would be pretty fucking rediculous.

First off, ouch. Second off, how egotistical can you be to assume your sense of humor is the touchstone of humor? Like, she actually feels her humor is perfect. The worst part is she truely truely feels this way.
