Is it just me or are these sorts of statements becoming more common? Another commenter on this post told someone he was lacking reading comprehension skills in an argument about the political implications of the children's novel Harry Potter: https://news.ycombinator.com/item?id=38904272

They're common enough to be explicitly proscribed by the guidelines.

I thought it was reasonable, and my post gives the evidence to back it up.

Maybe in some other forum, but on this one, it contravenes the guidelines, and probably cost your comment some support.
