if people believes this bs probably theres a guy working for the government thinking hey what news will we make up today, funny, terrorific, peismistic,optimistic....

As I pointed out earlier, all good and/or real text books will note the limitations and assumptions of idealized rolling and sliding friction. So only stupid people will "believe" that contact area has zero effect on the friction force. The same could be said about people who believe that intelligent people are the aforementioned believers.
