Satire? No way.
Dan Simpson's other editorials are extremely leftist - not Democratic leftist but Fist-In-The-Air leftist - so I don't think this is satire. Google up some of his other stuff, I don't see any satire.

As Sam Hoggson pointed out this is the gun grabber's complete plan, not just the "nose of the camel" that HCI usually shows us.

I thought it the plan was interesting in that he bypassed gun registration as a first step. After witnessing the wide non-compliance in Canada, he knows that it might not be the most useful first step to conficscation.
