Wow, I think you gave a way a bit of a tell with the bolded statement. That you only see homosexuals in how they might have a sexual interest in you.
I work with a lot of women. None of them I think of in a sexual way. In fact, I have a strict personal rule about not dating co-workers.
Since you keep focusing on that word "aberrant" so you don't have to say "icky", let's look at a dictionary definition.
aberrant (Noun)
a group, individual, or structure that is not normal or typical : an aberrant group, individual, or structure
a person whose behavior departs substantially from the standard
Okay, that logic, you could classify the left-handed, Mormons, the disabled, Redheads or blacks as "aberrant". They deviate from the norm.
Okay, how would knowing homosexuality exists ruin their lives. You learned homosexuality was a thing, and clearly it didn't ruin your life.
