The guy quoted hard data which backed up his statement yet people get offended. If it were about me I'd be more concerned about the test information and what needed to be done to fix it. But no, can't do that. So I guess the test information needs to be reprimanded too, along with any computers used, notebooks, pencils...burn it all.
Or the guy is an idiot and deserves to be able to keep promoting that fact.
Instead of getting offended maybe some people should do something productive and put that energy to use educating the people who drug the average down or teaching people anything for that matter instead of how to cry "I'm offended."
But no, the guy did a bad bad thing and shared an opinion that too many people don't like. Just ignore it, blame the messenger, and everything will be fine.
Some comments are racist, no doubt...but this isn't one.
