I'm not going to the link, but it's apparent that Rusty Shackleford gives aid and comfort to the enemy by spreading their terrorist recruiting propaganda.
I'd suggest going to the link, but not scrolling down to images. Then I'd suggest rethinking your statement about Rusty and his motivations for posting these images.
Aid and comfort is assigned to those who call murdering animals such as these "miscreants" and "youths".
