This sort of pettiness can make intelligent people look like children. When somebody feels wronged by something its very easy for them to think they're being victimised and look towards a conspiracy when in reality the truth is far more logical. If he took a minute to even think about this or do some research he would likely realise that there's likely nothing to complain about but that doesn't suit his agenda, and that's what conspiracy theorists do. They're not really interested in facts or doing any actual research just anything that might tenuously support their beliefs or victim-hood. He obviously flew off the handle and just sees this as another way to have a whinge about someone who he feels has it out for him but the truth isn't sexy and wouldn't do anything for him so it's irrelevant.
