Replying to How can someone be so stupid

I was talking to one of my boys while walking through my mountain's parking lot today, and a bird was walking near us. I told him to be careful because they're programmed to strike if you get too close, and he looked at me with a confused expression. "Programmed?" he asked me. I said, "of course," every person with half a brain knows that birds aren't real, and they're really just spy drones created by the government. He said "you must be joking" and I then quickly ended the conversation because I couldn't believe someone could be that ignorant, especially here in the bozone. How could anyone actually believe birds are real with the overwhelming evidence that the last birds were genocided 20 years ago and are now all robotic replacements!? How can such a person even function in the real world if they can't open their eyes to reality?
