I'm one of those people. Allow me to respond.
I have seen people ruined with medical bills.
There are many reasons why the system is dysfunctional, and I'm aware of nearly all of them.
Did you know that a round of cancer treatment in the US can cost over $500,000, and even if you are fully insured with a good policy you can have a 20% copay required, meaning that with insurance you still personally have to pay $100,000 or more? That sort of thing is what is bankrupting people and is why most medical bankruptcies involved people who were fully insured.
That's assuming your insurance policy wasn't subject to "recission", which is legal retroactive cancellation of the policy as soon as you have any condition like cancer that would cost a lot to treat.
We have a for-profit medical industry, and a for-profit insurance industry and both are motivated to increase profits, and reducing care is often a way to do it. Even non-profit hospitals will price gouge. Non-profit status does not mean that the executives working there aren't paid large salaries, it doesn't mean that things are delivered at cost, or with minimal mark up.
The "reform" is mandating people buy insurance from for-profit insurance companies, with no cost controls. Thus we end up with policies that can cost a family $20,000 a year in premiums, while still having large co-pays that can bankrupt you. The parts of the law that would have provided socialized care for the poor were gutted by the Supreme Court review, and by the executive office rule directives interpreting the law.
The answer to the problem is single-payer. The reform system is a further bailout for industry and is already driving up costs and reducing the number of insured.
Your posts presents those of us who support a reasonable working solution of single-payer as a position of hypocrisy, inconsistency, and/or ignorance, because we don't accept a non-working solution that retains and increases out of control costs and profits for industry.
Not supporting a specific, bad solution does not mean one does not see there is a serious problem and reform is necessary.
