These conspiracy idiots have always been around. They must go around with hate in their hearts. When 26 people were murdered at Sandy Hook Elementary School, including 20 precious little first graders, one hateful wack job started claiming that it was a hoax. Before you knew it, every hate monger around started believing it. Parents of the murdered children were getting death threats for creating a hoax.

Then of course there are all of the hate mongers who insisted the Holocaust was a hoax. It will never end. Children murdered. Deny it. Nazis murdered millions of Jews? Pretend that it never happened. Over a million Americans died from a virus? What? That never happened!
Ignore them. If you listen to them or reply, you give them credibility.
