What makes homosexuals different from pedophiles, sadomasochists, etc is that we have at least some evidence to support the idea that homosexuality could be attributed in part or whole to biological factors, while we have no such evidence to support a biological connection to pedophilia, sadomasochism, and so forth.
Well, in case haven’t heard, a large percentage of pedophiles were victims of child abuse, so I would definitely qualify that as “life experience”. As for therapy, I’m not suggesting that pedophiles might be able to find normal attractions, but therapy might be of help in the way of controlling their (unfortunately dangerous) desires. I suppose, in some ways, pedophiles and homosexuals are similar. Both have extreme stigma and prejudices attached to them, both are unlikely to be “cured” through therapy or any other means and both have trouble sustaining normal heterosexual romantic relationships (albeit, in the case of homosexuals, this is absolute). This brings me back to an earlier point. We are a society of labels, and the labels geared towards one’s sexuality can be particularly harsh. As a church, we should strive to separate the labels from the people being labeled, to separate the sin from the sinner, and see these people, no matter how disordered their actions may be, as normal people with abnormal problems, not “pedophile Bob” or “S&M Jane”.
