"These people have a very serious problem, and they need treatment,"
Yes, Jenner does have a "problem". She was born into a body of the opposite sex. She is seeking to "fix" this by transitioning.
Of course, Limbaugh is probably suggesting transgender people need "treatment" in the form of conversion therapy, even though it has been shown to be completely ineffective and also harmful, but hurting people psychologically will help them, right? That's genius! So much money has been wasted on psychological and medical research to find "cures" for things when the only "cure" needed for anything is coercing people to act "normal"!
