When have you been stopped from saying anything you want?
Right here on this web site. Go ahead and try and type the word N!gger, even if you are joking around. Nope, no cigar.
Our nation has lost all sense of humor. There is a governor on this site that automatically censors all sort of things you can type, and that applies to the real world.
Some things you can say in polite society, some things you can't. As a nation, we have lost our sense of ownership, our personal sense of self-esteem and we have VERY THIN skin.
I don't hardly spend any time on FB, but I have some friends that do. They tell me you can type things like "cock sucking mother fucker". . . but you can't call someone a "whiny faggot", or a "dumb n1gger," you're likely to get the post reported and have it yanked. I'm not sure if that's true, but that is what I have been told.
