You are out of touch with reality if you believe that statement to be truthful.
You are out of touch with the theory that transexuals and homosexuals follow. From their perspective, the perception of one's sexual preference is set in stone, at conception. Therefore there is no conversion, but there is open acceptance of what is set in stone. They argue they are simply removing the social stigma that demands people not be honest with their natural sexual preference.
Now, as a Christian, we can acknowledge that our human nature is, at conception, born in sin, under the curse. If there are natural sexual preferences, they are corrupted by our sin nature. Thus, if you are attracted to the same sex or feel like you are a different sex, this is due to our corrupt nature. If one is attracted to the opposite sex, that attraction is still corrupt due to our sin nature. Therefore, as Christians, we must subject our attractions to Christ and His command for sexual behavior.
If one is not a Christian, it will seem foolish to them that our nature is corrupt. They will think it is perfect and will argue such.
So, no, they are not trying to "convert" your children.
And no, I am not naive.
