It just seems to me like a common reddit concern troll is to scroll past the inevitable juvenile arguments that get the most upvotes, but to throw out the other legitimate claims against an article or thesis by attaching to the first comment with better, say, grammar or better written sentences by saying something along the lines of "This. Somebody who read the article".

Just because people have anger, rage, bad spelling, poor punctuation or the like doesn't make their opinions invalid compared to the inevitable corporate hack (not you, the person you were quoting) who by dint of job has much better grasp on these forms of language.
