I dont think an angry mob has ever chased naruto cause if the 3 hogake didnt allow talking about kyubi, i dont think he would allow them to hurt Naruto.

The questions about Naruto past and that fateful day wil be answered maybe even in the next arc if the arc is about Naruto and Akatsuki,cause someday soon the mangaka must tell us something about Naruto. If he doesnt he isnt the smartest mangaka...
