The things going on underground alone would cause most to have a heart attack. Then you add in the reverse engineered crafts and mind control tech that allows abductions/implanting/impregnation to take place. Blood types. Tracking viable organ donors. Tunnels. Loosh. Baal. It goes on and on and most just couldn't/wouldn't accept it as real.
I wouldn't worry too much about one troll. Your art is great. Your child is loved. Don't let one moron ruin your day. Life is too short. God bless you.
