La'Porsha is consequent in her logic. She believes having gay sex is sinful. So she won't support it. I am sure she doesn't see it for self-identified adulterers or other active sinners either.
Regardless of that something should not be deemed ethically acceptable on the merits of natural it is or whether it is by choice, that is stupid. Things can be innate like pedophilia and still wrong to act out on, things can come from your environment like maybe certain music tastes or hobbies and it is totally ok to have them.
The parameter of being born this way or not is irrelevant when it comes to moral acceptance.
