The land of the free and home of the brave has always been like this. Read about the politics surrounding the Spanish American War if you have any doubts. Or maybe about the Salem Witch Trials, or "Judge" Roy Bean, the self-appointed "Law West Of The Pecos", who killed people without any legal backing. How about Wounded Knee or The guys in Texas who dragged that poor black fellow behind their truck until his body disintegrated?
No, these things have always been with us, but today with instant communication from everyone to everyone, these things either become anathema or they become popular immediately.
That little girl in another thread cursing and showing her body in an internet video has always been around in American society. Fifty years ago though she couldn't reach a mass audience like she can now.
I guess we can eliminate TV and the internet? Maybe then we can go back to having small-scale perverts and jingoists instead of large-scale ones.
