Heresy hunters would do well to remember the quote below in regards to those they attack. I think they believe those they attack to be ignorant, immature little children that they must enlighten. When, in fact, they are reasonable adults who are able to make their own decisions and, in turn, live with the consequences.
"A child becomes an adult when he realizes that he has a right not only to be right but also to be wrong."
