Not to mention, if that poster would have done the littlest bit of research, he would have found that compared to most democratic countries, the POTUS has very little power compared to other Western powers.
The Prime Minister's office of Canada for one has incredibly more power then POTUS. It is common knowledge for many, at least here.
So all that talk of centralized power is simply not true, and can be verified quite easily.
But people will only see what they want to see. Some will make an effort to research though, before assuming, judging and convicting.
