If I had a daughter I’m fairly positive I wouldn’t want her marrying an ex-gay. Besides - most homosexuals won’t want to change their orientation through therapy and giving the state or any other authority to compel people to submit to therapy reassigning their sexual orientation is not something I want to see since heterosexual orientation can presumably be changed as well. Absent a state interest sufficient to compel somebody to undergo this sort of therapy I can’t see most people saying that any establish rights granted to gays should be revoked as it is now “merely” a choice.
Nobody is talking about forcing anyone to accept recovery therapy -- far from it. The force is coming from the gay lobby, insisting that homosexuality is irreversible, and therefore they deserve not only gay marriage and adoption, but also to indoctrinate children to accept their lifestyle as "normal."
Homosexual advocates here in Maryland have tried to introduce a school curriculum that not only promotes a positive view of homosexual behavior; it named certain church denominations as "bigoted." Even in one of the most liberal counties, it was shot down, but they try again every year to ram it through. The extremist gay-favoring school board will not allow equal time for the message that change is possible; and have repeatedly rejected requests by groups such as Exodus or Parents and Friends of Ex-Gays to also take part in the curriculum.
In other parts of the country, Christians or others who believe it is possible to recover from same-sex attraction have been the targets of discrimination and expulsion from PhD programs in Counseling when they could not guarantee to affirm patients with gay orientation, and tried to find a gay-affirming counselor for them. Instead, persons of conscience were harassed and/or dismissed from their doctoral programs after years of work and effort. Lawsuits are ongoing. The gay lobby wants to set orientation in stone, with obvious advantages for them politically, regardless of the truth or the desires of those who may be in it only because they lost their way, took a wrong turn or were abused in childhood and are compensating with unhealthful behavior.
