In the larger scheme of things, it might not seem like a big deal. After all, what harm could it do? Blonde girls know they're smart even if people generally think that telling "dumb blonde jokes" is okay, right?
Or maybe not. A put-down is a put-down, no matter how harmless the intention. If I had a blonde daughter, I wouldn't want her within hearing distance of someone inferring that blondes don't have a lick of sense. Children have a hard enough time growing confidence as it is, without having adults knock them down.
When did blonde jokes become popular? I don't know - I just know that I have endured them for far too long, smiling politely while wanting to conk the offending jokester on the head. What could they possibly be thinking, telling a joke like that to me?
You may be thinking that I have no sense of humor. You would be so wrong! I laugh at the most obvious of amusing things, and at the least obvious. I find mirth everywhere. I try not to laugh inappropriately. Sometimes when I am under stress, I find myself laughing uncontrollably, because suddenly lots of things seem funny. I guess that's a good stress-reliever, so I'm okay with it.
But wait - what does NOT telling blonde jokes have to do with anything? Well, it has to do with being aware of your words and your attitudes. This covers most anything - like my mother always said (and probably yours, too), "If you can't say something nice, don't say anything at all."
The only way to grow and evolve as a kind and enlightened human being is to pay attention to the kindness of your actions. And since learning how to be more "present" in this world leads to greater happiness, I encourage you to pay attention.
You never know what you might learn.
