Part of the hostility toward homosexuality comes from the common assumption that it is a 'lifestyle choice'. Realistically speaking, someone cannot just "decide" to be gay. If someone maintains that he or she is gay, but is not attracted to members of his/her gender, then he/she is not indeed a homosexual. Voluntarily identifying with the gay stereotype and realizing that you are sexually attracted to your own gender are two very different things.

If parents raise their children with the stringent expectation that their children are supposed to be heterosexual, and if any of their children are actually gay, then it will only hurt those children in the long run. If children are raised with the concept that it is "wrong" to be gay, and they subsequently discover they are gay, they may ponder or even commit suicide. That type of upbringing also may instill anti-gay sentiment in siblings or other children toward their gay peers. This is why children can be so hostile toward peers who are gay, or even when children simply suspect that their peers are gay.
             How does one know if being homosexual is not a choice? Do heterosexuals know that if heterosexuality is a "choice"? And how do we know for sure that people are not born gay?
