Actually I did. The exact quote was:
This means many individuals lose their insurance if their company downsizes, and then when they try and get new insurance if they have a pre-existing condition they are denied coverage or quoted a massive rate. This is the case even though the condition did not predate their work insurance.
I've bolded the part where I said pre-existing condition in the original post, although it was not bold initially.
Also you might want to be precise on what the statement "deny health care" means. It is quite legal in America to let someone die of a terminal illness that would otherwise be treatable. What isn't legal is for a hospital to have a heart attack patient show up at their doorstep and refuse to treat them because of financial issues. You also can't have severed limbs reattached without first providing insurance information that checks out.
So I certainly disagree that in America it is illegal to refuse health care. A hospital can turn away someone with a severed limb as long as there is no concern about them bleeding to death. If there is they can treat the bleeding in the cheapest way possible even if it were to prevent reattachment of the limb and send them on their way.
That doesn't meet most people's definition of health care. And if it meets yours we probably need to have a discussion on what health care actually is.
