Are people born gay? Some say yes (including many people within the LGBT community). Others say no. But the truth of the matter is that is there is no scientific evidence to support the existence of a gay gene. Even the American Psychiatric Association (which removed homosexuality from its list of mental disorders in 1973 after pressure from gay activists) admitted that people are not born gay. Thus, it is just propaganda created by the LGBT community to gain support and sympathy, at the same time silencing any skeptics.
In addition to the gay gene not existing, there are many former homosexuals out there, which proves that people can change their sexual orientation, sometimes via therapy. These individuals are targeted by gay activists because 1) they abandoned the lifestyle (hence betrayal); and 2) gay activists want to force them back into the closet and then claim that there is no such things as an ex-gay. Such targeting ranges from harassment to physical violence. Gay activists even shun them or prevent them from being at events where gay rights groups are present.
In addition, gay activists try to forbid those in the psychological and psychiatric fields from providing therapy to any gay or lesbian (even if the gay or lesbian requests such therapy). Needless to say, they are determined to keep the public from knowing about ex-gays. Fortunately, for the ex-gays, there is an organization known as PFOX (Parents & Friends of Ex-Gays and Gays) to stand up for their rights. PFOX’s website can be found at http://pfox.org.
Being gay is a choice, it is not a matter of genetics. It can be the result of environment, whether it be an individual’s upbringing or exposure to the gay lifestyle. Sometimes sexual assault is a factor (erg. some women who were sexually assaulted or molested as girls become lesbians because they develop a hatred of men).
And when does one became gay? Some say it is when one develops a sexual relationship with someone else of the same gender. Others consider physical affection (erg. kissing). Still others say it is when one develops an attraction towards those of the same sex. It is perhaps a combination of all three scenarios.
So you can put the idea of the gay gene in the same boat as global warming (a load of hot air) and evolution (which is just a theory with many flaws). In fact, Ben Stein (whose documentary Expelled: No Intelligence Allowed focused on the suppression of intelligent design by the evolutionists) should do a documentary on the gay gene.
