Answer: Homosexuality is not typically considered as "sick" as incest or child abuse, which are mainly heterosexual.
Step-by-step explanation:
Claiming that homosexuality is not as bad as incest or child abuse, is not an objection, but rather a justification, to the disapproval of homosexuality based on nature.
Even if homosexuality is presented as the least problematic, that statement reflects the underlying homophobic idea that those three acts (homosexuality, incest, and child abuse) are comparable and part of the same spectrum. It implies stereotypes that represent homosexuality as a sexual transgression.
