right and wrong way to get attention

Okay protests are great, don't get me wrong, and since the media often pays as much attention to the protesters as the actual program its a successful way to get your message across. BUT bringing assault rifles, even in open carry states like Arizona, is a dangerous way at getting attention.

You don't need to go to these extreme measures to show your point of view. If anything it makes you, and your message, seem less legitimate. Instead try organizing, pass out leaflets, use word of mouth, but not publicity stunts.
