It's all about the money...
Any page you go there has a "Donate Now" link on it.
They attack the western states more because of the percentage of public land. They feel like that gives them entitlements... Even though the vast maojority of them do not work, pay taxes, or own their own property.
They know they are liars as well, but as long as they tug the heartstrings of some housewife that doesn't know any better and get them to donate $20 to them, it is worth it to them. They don't care about anything else.
Follow the money.
