Great video, I especially liked the part about the National Anthem, for years I've been thinking and saying similar things, sometimes even toning it down to avoid arguments when I felt the urge to say something.
One time I mused to someone, and it was someone that wasn't even very patriotic, "Don't you think it is ironic that they want people to revere the nation, and when they send kids to school they play the national anthem at the start of the day, they send them to a place they hate and then the theme song is basically a prayer to the nation. Doesn't seem like good publicity."
And that person, not even someone very patriotic, got all pissy and said "If you don't like your country you should find an other" I was like wow, the brainwashing runs deep in this one.

It all seems like many people just love symbols that enable them to group up and divide themselves from outsiders, and then jerk themselves off for how great their group is just for doing that, then on top of that making everyone show signs to devotion to the group.
It's not good for anyone, and it's pretty lame and looks really outrageously insecure... but then again, considering how lame it is, it shouldn't be surprising people act so insecure about empty symbols like national anthems.
