That's what they want. It's how the prey on their followers. They take the most basic animalistic urge that all species have, the urge to procreate the species, and tell you that you're flawed for that urge. Oh, but don't worry, they have the only cure for your flaw. It's why they hate the people who have come to accept their own sexualities. Those people have broken free from the trap that the evangelicals are stuck in.
