Okay, but what about people in other countries? Why don't we have an obligation to help them, to?
If it's not clear, my tongue is firmly in my cheek as I say that, but where it isn't in my cheek is when I'm telling you some people don't just buy your simple pro-universal-healthcare argument wholesale, especially when you refuse to defend it against valid questions like this.
Universal healthcare would be great if it was cheap and covered everything.
I'll offer some advice, although I doubt you think you have much more to learn in life. If you're walking around looking for donations or support towards a cause, perhaps mocking those who may not share the identical philosophical beliefs as you isn't the optimum approach.
