Yeah, it is ignorant.

What if you got in a car accident and you were going to die unless removed from a burning vehicle and the person who saved you was a child molester? Does that make them a good or a bad person? I don't agree with child molestation, but how do you know those people don't have mental problems that we haven't discovered yet? That's definitely going out on a limb, but your rebuttal was childish and stupid. There is a difference between doubting something that is fact and known compared to something that nobody knows the real answer to, therefore making anything possible.
