Well, no, Sam, that’s just false. Allowing private health care to expand does not amount to dismantling public health insurance. That’s logically equivalent to saying that allowing companies to hire private security guards means you’re dismantling the police.
You know as well as the rest of us do that Canada has no plan to dismantle, or even significantly cut back, public health insurance. You know as well as the rest of us that there’s not a single politician in Canada who has seriously proposed it and that anyone who did would be out of politics in weeks.
Now, as for the OP, I don’t understand the pitting. Palin is opposed to public health care (well, unless it’s for old people.) This is hardly news; it’s the standard position of her party and has been her position, so far as I am aware, for her entire career as a public figure. She was asked a straightforward question on a matter of policy and answered honestly. She’d be a liar if she had responded in any other way. One might disagree with her, but that’s hardly a pittable matter.
For that matter it hardly constitutes interference in Canadian affairs, it’s just an opinion. If you asked me “What should the United States do with regards to capital punishment?” I’d answer, honestly, that they should not have capital punishment. It’s not my decision to make but that happens to be my opinion.
