@turkel, no one is attacking you
I'm not sure if you read my post previously but my healthcare is covered 100% by my employer. So I, like you, am one of the lucky few. But just because I'm lucky does not mean that I don't see friends and relatives suffer from the way our healthcare system is organized. I can see that and, despite my own ok health insurance situation, I can be motivated to work to fix the problem- because I want what's best for my fellow Americans, not just what's best for me personally.
I would suggest that you were the one who infused the emotional concept of patriotism into a fairly bland conversation about health insurance and implied that folks who saw positives in the healthcare systems of other countries are somehow not "proud Americans". So I'd argue that your comments are evidence of the reason that things don't get fixed in America- its easier perhaps to characterize the other guy's position as unpatriotic so that it can be written off rather than considered on its merits. And then to feel "attacked" when someone calmly pushes back. Food for thought.
