You don't need to censor the nutbars, and it is ok to call them that.
The former is shutting down discourse, the latter is pointing out its flaws, and is a correct response.
When I was in high school, pre-Internet, we has an entire class about modern media.
We discussed advertising, profit motives, watched TV commercials and dissected them, it was all about creating awareness in youth, about something they grew up with and took for granted.
This sort of thing had value, it helps people see things through a different viewpoint, including helping people become more critical of the snakenoil salesman.
We should have such things about the Internet, and youtube, as well.
I bet the average Joe doesn't realise how profitable YouTube channels can be, and thus, how profitable lies are.
