Why does sexuality have to be an issue at all?
No heterosexual is identified solely by his sexual orientation; yet for most on the right the homosexual is identified only in the context of his sexual orientation, which is no more significant than that of the heterosexual.
Sexuality doesn't have to be an issue.
On the other hand, there's no reason it can't be discussed. And in those discussions, most people seem to want a person's sexuality to be seen as always a choice or always a genetic trait. Why is that?
Because sexuality isnt discussed in good faith, in an effort to learn about those perceived to be different; rather, its needlessly contrived into a political issue by those hostile to gay Americans, the OP is evidence of that.
Social conservatives put forward the failed argument that if one decides to be gay, and sustains discrimination accordingly, all he needs to do is stop being gay to end the discrimination. This failed argument is also used by social conservatives to seek to undermine the civil liberties of gay Americans, Utahs Amendment 3 is an example of that.
This also exhibits the ignorance of most social conservatives where 5th and 14th Amendment jurisprudence guarantees each person the right to expressions of individual liberty, free from interference by the state. Whether one decides to be gay or is born gay is therefore legally irrelevant, as one is entitled to Constitutional protections in either case. See
Romer v. Evans (1996),
Lawrence v. Texas (2003).
In the OP we see a variation of the decision canard, where hapless homosexuals were born straight but compelled into the gay lifestyle against their will as a consequence of being molested this fallacy concludes that if we could only end child molestation we could also end the dreaded curse of homosexuality.
Needless to say the OPs premise is ignorant idiocy, its insulting to gay Americans, and exhibits the contempt most on the social right have for our Constitutions guarantee of the right to individual liberty.
