Irrational speech or stupidity to you may be logical to someone else. While it may be stupid to joke about it free speech is denied if you cant say it. Making a joke hardly endangers a life. Do you really think a guy with a bomb strapped to him is going to be joking around? Hes got one thing on his mind and thats completing what hes there to do. Kill maim or injure as many people as possible for whatever cause.
