I would like to make an update. I found the source of PastorDave's avatar. The source picture is of an actual pastor. I contacted this person about the troll who was misrepresenting him on an online forum. He replied promptly. He is not PastorDave, he has never posted on this forum, and none of his children have been involved with drugs.
So yeah, whoever posted here was definitely a troll who stole someone else's identity.
