Why do people hate me for being blonde?

I always get people making cruel jokes at me just because of my hair colour. It's so unfair. Why? Why do I have to be regarded as dumb before I even say a word. Look at hillary clinton and marilyn monroe. They were and are both very intelligent people. It's just so cruel. Who ever started these jokes should be imprisoned. Why us? Why does it have to be us blondes? What have we ever done to deserve this? Just today, I heard someone mocking me as I was leaving the Walmart store. I guess it was because of my hair. WHY?????
