That article is highly ignorant in its premise that it is only Americans who act this way, and in the misleading way in which it presents its initially described demographics through less than thousands of tweets and posts from "Americans." The post is highly flawed.
I find the people quoted to have said something extremely stupid and worthless, however, the original poster is quite oblivious to his/her own pretentiousness.
Public Shaming also appears to not be open to public reply, which discounts both its name and any qualifications as a legitimate source of criticism/studies.
