They may be as high as 2% or even 3%, but it is only about 1/3rd of them which are disgustingly obnoxious about it.
A business associate of mine from a previous life had that illness and admitted it was a mental illness. He despised that 1% more than I did and said they discouraged people like him from getting the help they needed.
He kept his problem under control only by avoiding them like the plague but wished he could have a normal heterosexual relationship. He was afraid to pursue such a relationship, however, until he was sure he would never go near the gay sewer again.
I'm sure there are others like him.
As with any other sin or addiction, you can’t fight it of your own power, or else it comes back 8 times worse (the demons and the clean house).
Taking it to the cross is the only way out.
