How do you easily get rid of gum in your hair? Cancer
Do you understand how saying something like this you might hurt someone who is suffering or struggling?
It's just a joke. Why do you get so offended?
It's not personally offensive to me, but there are a lot of people in the world who have suffered from cancer or know someone who has. To imply that it is a choice that someone can make if they don't like their hair is badly trivializing everything that they have gone through. If you talk to someone who has had chemotherapy, they could tell you that losing their hair was the least of their troubles.
I wasn't implying that at all. I told you it is just a joke.
Jokes about cancer are not going to be funny because cancer is such a terrible disease.
