What do you call it when a transgender person gets mangled in a car crash? A gender bender!
Are you making a joke about a transgender person being hurt in a car crash?
It's just a joke, you shouldn't take it so seriously.
Making a joke about a transgender person, or any person being injured in a car accident is not funny. It's not funny to laugh at someone being in pain and suffering. What if this happened to one of your loved ones?
