I think they just cut and paste from one site to another. I know i've seen that Teddy Rosevelt quote thrown at Jim Rob at least half a dozen times by this crowd.
"We reserve the right to refuse service to anyone."
Jim's site, Jim's rules.
Trolls and real frothing-at-the-keyboard types can expect to get zotted.
I have seen a fair amount of relatively civil discourse, and some less so, but that keeps things interesting.
Most of them (on the site with the article) sound as disaffected as liberals...sour grapes make bitter w(h)ine.
