I have my own opinion of your splinter groups aka

CAIR however is neither. CAIR is primarily a civil liberties organizaton and as such teaches civil liberties to Muslims in America, some of who have no idea what a civil liberty is. NOTE:
I do not need their services LOL.
One of them is the civil liberty outlined in the 5th amendment. Sometimes cartoons are used to make points. Like for instance using cartoons of say crosshairs on congressional districts when they are represented by someone of another party. Just making a point. Not tasteful, but not wrong (or illegal) either.
If your opinion is that this liberty is not important then run for office and get it changed. There is a clearly outlined process to repeal it. Repeal enough of them, and what do you have then?
Good luck with that.
