While my “straight” conservative Christian friends readily argue that “gay” people can be converted through various therapeutic means, they never mention what this logically entails for their own sexual orientation. Simply stated, it seems reasonable to say: If a “gay” person can be converted into a “straight” person, then a “straight” person can be converted into a “gay” person. Even though my conservative friends don’t explicitly talk about this concern (that they might be converted to “gay”), it does seem to come through in their everyday practices. This fear of conversion helps explain why many “straight” conservative Christians keep their children away from people who are openly “gay”—I’ve seen instances in the news where “straight” conservative Christians don’t want “gay” teachers in the classroom teaching their kids, they don’t want “gay” daycare providers or babysitters, they don’t like “gay” politicians and “gay” actors and actresses setting bad examples or celebrating the “gay” lifestyle. All these fears, in seems to me, are related to a fear that their children might be converted to a “gay” sexual orientation.
One might think, from this person's view, that he or she had never been around parents, or adults in general. Perhaps not, but that would be quite remarkable. Considering he cites examples he has seen on the news, he must have had at least that much exposure to parents.
Because nothing is more natural or understandable than the parents should show concern for whom their kids are around. If, in the paragraph above, we substitute, let's say, "drug use" for "gay", we would find nothing remarkable about the parent's concerns for any of those things.
In an interesting way, “straight” conservative Christians who advocate the notion that sexual orientation is changeable are implicitly taking a social constructionist view of sexuality and gender, which is much closer to a postmodern way of thinking than most are apt to admit. On this view, sexual orientation is in whole or at least in part, a product of various choices and ways of thinking and acting.
No, they're acting no different than parents have since probably not long after the Fall--parents know that children can influence by those around them, particularly authority figures. The only "new" thing about all of this is that the homosexual lifestyle is "politically correct", and to try to ward one's children from it would likely be considered a hate act.
