Reading through all of this, I’m not sure what to say, but there are a couple of points worth throwing in.

Regarding “homophobia”, the word has its origins in the early twentieth century, but was initially used to describe a paranoid or irrational fear of human beings. It was, then, a darker version of “misanthropist” — a person who hated humanity, but about whom there was nothing charming. It was used in the context of discussing militarism and genocide. The term was first used to specifically mean a fear or irrational hatred of homosexuals around 1970, and within the specific context of the campaign to remove “homosexuality” from the DSM. Given the original usage, the word was obviously very loaded and has continued to remain so — a word that often is more likely to produce emotional responses on either side than thinking ones. As commonly used (and as it has been used in a few cases above) it often ends up being a dismissive term of moral condemnation, which is hardly a good starting point for serious dialogue.

As for biology and destiny, there is one inescapable fact: we all die.
