Proof that homosexuals are capable of understanding natural law

Proof at Crisis Magazine that at least one formerly homosexual man converted to Catholicism, and to heteronormativity, due to natural law arguments. That's been the strange thing about this debate for me all along, the insinuation that homosexuality is such a mental illness that it actively blocks the ability to understand natural law reasoning. It is a mental illness, but it isn't quite that much of a pervasive developmental disorder.
