There has always been the eccentric tin foil hat wearer, handing out pamphlets in the market square on a Saturday to anyone that will take one, but now they have the Internet. With the Internet a small minority can suddenly make a disproportionate amount of noise. It's still noise of course, Elizabeth I was a man, flat Earthers, anti-vax, anti-<insert random pet peeve>, mind altering con trails, Lizard people etc. Now the crackpot is no longer harmless, they can now spread misinformation at an alarming rate, and that is always going to be the worst aspect of the Internet.
