As a blonde male I don't mind blonde jokes because they provide dingy run of the mill dark haired individuals (who typically have low self-esteem), with an opportunity to feel superior to someone else for once in their lives. More importantly, these jokes are typically aimed at blonde women and that's as it should be. ( kidding)
Example:
A blond woman speaking to a ventriloquist who's act was filled with blonde jokes :
Blonde: "I’ve heard enough of your stupid blonde jokes. What makes you think you can stereotype women that way? What does the color of a person’s hair have to do with her worth as a human being? It’s men like you that keep women like me from being respected at work and in the community and from reaching our full potential as a person. Because you and men like you continue to perpetuate discrimination against not only blondes, but women in general, and all in the name of humor!"
Ventriloquist: "I'm sorry ma'am but..."
Blonde: "You stay out of this, mister ! I’m talking to that little idiot on your knee!!
