False claim by YouTube, +18 age-restricting News videos!

Sure the protesters in Iran, shout slogans, throw stones and set fire on their Scarves, shawls but such activities are normally shown daily on TV channels around the world. Documents, news, movies and shows are full of such events and the News TV channels are live broadcasting on UA-cam as well but they are not age-restricted even they shown exactly the same or identical videos. Sad to say UA-cam age-restricting our videos which hardly coming out of Iran (Islamic regime has shut down Internet for hiding the deadly crackdown). In another word, UA-cam kills the news videos from Iran, helping the barbarian Islamic regime by putting +18 on such videos without enough evidence. If throwing stones is classified as violence, then how else can the protests in Iran reach other people outside of Iran?
