Coming from a country of people with dark hair and skin, I don’t really get blonde jokes. Then again having known enough turbaned people I never got Sikh jokes. I just know if you aren’t making a majority you will be singled out and you will be made fun of.
When this is taken personally, defence mechanisms come into play. Since I am not a tall blonde doesn’t mean I am going to make fun of you. No need to get nasty. Doesn’t make you look any better or smarter.
