There is a problem with this argument:
And it can be summed up as follows: you read newspaper articles online, yes? And you know full well that the comments sections to said articles are universally filled by crazy people who write like they had to cram to pass the Turing Test, yes? And so you know to either not read newspaper comment sections, or else simply skim them for particularly good examples of Teh Crazy, yes?
…So why are you assuming that you’re unique in all of that? – Because, well, you’re not.
PS: I don’t care how dumb you think that the American public is; they’re still smarter on the average than the subgroup of people who comment on online newspaper articles.
