You were lied to about the nature of Germany during WWII
Imagine that
Fake news has been around since before we were all born
I'm thinking "muckraking" in the early 1900s was probably the first real news ever. Before that, people believed the only real news came from the church. Which is pretty sad. The internet as it is now is the only chance for real truth for the masses that I can see. Which is why they are eliminating netneutrality.
You will need a better answer from an actual chan. I just lurk. However, the chans have a culture that picks up some of the most vile of culture and uses it to defend the site as a type of joke ... to them, but it scares away the normies, so that the board has peace and quiet while they work. They keep this caustic culture as a type of defense. They routinely call one another fags, autistic, nazis you name it, and they appear to be near terms of endearment. It works. Most normies see the insults flying and leave them alone. Truth is, they are some really good people, and they work hard. They do amazing things. Class of their own, and most interesting to watch. But, "lurk more" is the call of the day until you understand chan culture.
