Green Day Pissed at Wal-Mart

Well it looks like Green Days Latest Album "21st Century Breakdown" will not be on the shelves of Wal-Mart due to the parental advisory sticker it would have to have for having curses and some references considered about adult activities. Well I guess it is okay that Wal-Mart sells Rated R movies where there is full frontal nudity, violence, blood, racist, and cursing in them though? Where is it that you draw the line on what to sell and not to sell because of free speech?? Well to be honest Green Day they would probably sell your new album for $9.88 like they do all the other albums and you wouldn't get as much royalist from it anyways. I think it is good that Green Day has stood up to the big bully Wal-Mart.
