The best thing to come out of this thread has been the remarkably measured responses of some people. How do you stay so calm and type a proper response when someone denies the moon landing or starts with the old MMR thing? Usually for me the red mist descends and I lose control. 
Clearly the moon landing/MMR people are intensely ignorant. It would take 2 seconds of internet research from a decent source to fix the problem.
The MM, Sandy Hook, 9/11 inside job people are repulsive. The end.
The Diana one I get because she specifically said she thought she was going to be bumped off in a car accident before her death, however I don’t believe it actually happened. They would have literally nothing to gain from this and everything to lose. She wasn’t pregnant and Charles was bonking Camilla before he was even engaged to Diana. He never stopped! Why would he suddenly want her killed over it? I know he’s a bit of a jerk but to do that to his own children? Why on Earth would he bother? And the Queen? She’s the actual Queen! Diana was just some annoying rich girl with no power whatsoever by the time she died. It’s a tragedy for her kids and that’s all it is.
The most irritating one on here (as far as the stupid and laughable rather than offensive goes) is the Queen Elizabeth was a boy one. Wtaf? Is it so incomprehensible that a woman could run the place? How insanely offensive (yes, actually this is offensive too)! Do you really think none of the men and women who took intimate care of her, dressed her (!), examined her, hadn’t notice she had no breasts and a penis? No periods? Come on! That’s the stupidest thing I’ve ever heard (which is really something after reading this thread).
Pretty much all the child abuse ones I believe, sadly. Just a bunch of cover ups from rich men. Poor Corey Feldman has been talking about it for so long. I’m glad people are finally listening to him.
It would be good if people could start to give actual reasons for a conspiracy taking place, rather than “I can’t put my finger on it” or “it’s just a feeling I get” or “it doesn’t add up”.
