And RE: the edit I just noticed that you made, you appear to have confused "propaganda" and "politically incorrect" with "factually correct".
A claim was made and backed up with data-driven scientific study and you still aren't able to perceive it as anything other than propaganda? I feel sorry for you.
It's a reasonable post that makes points I, frankly, am not qualified to judge, so I will not try to.
Your post stated that the author had provided no argument nor data, when it did exactly that. I am able to judge the existence or non-existence of text, so I replied.
