I know, which makes it difficult for those of us who do.
And that is the problem. Many of the pastors that are attacking evolution know nothing about it from a scientific view and to make matters worse, their theology isn't very good either.
The internet has really helped to expose the weaknesses of most pastors. I can't even remember the number of times I've heard them cite some "fact" that ended up being an urban legend. They have even made the mistake of telling the story as if they knew the person it happened to. Urban myths about missionaries are very popular.
I've also heard the story about how NASA was befuddled because they couldn't launch a probe due to a missing day. Conveniently a Christian was in the room and he reminded them that God once made the sun stand still. Ends up the NASA calculations were perfect after plugging in that "data". I still see that story repeated here sometimes...
Sunday school teachers are even worse. They are usually just somebody's mom or when it comes to singles, a peer that wants to score with the women. Their knowledge of theology, science, history and current events is very weak yet they are seen as an authority.
