Back to the idea that in your country the government doesn't have the peoples' mandate for healthcare. If that's the case, surely you can agree that there are some places where healthcare has been placed under the control of the government -- like France, Britain, or indeed even New Hampshire to an extent. It then seems to me that the democratic process is what determines what powers the government has, and in many places, the citizens have democratically given the government the mandate to provide healthcare.
Here's the rub: It appears to me that your country, despite how you feel, has given your government the mandate to provide healthcare, by electing someone running on a platform that includes government healthcare.
It then seems to me that, as this man, democratically elected and very open about his intention to bring government healthcare to the United States, has his mandate, he can and indeed MUST try to implement it.
Therefore, it seems to me that your country wants and is going to get government healthcare. Where is your issue with this?
