The particular HN user to whom you refer as "people like you" has a unique experience with homelessness and that's why she has a unique perspective on some issues related to the topic. I used to butt heads with her on certain comment threads until I Googled her and understood that. I think it's kind of cool that someone in this forum can present those views in the way that she does.
Regarding healthcare, there is no shortage of alternative solutions proposed for the improvement of the American health insurance system. If one party's leaders close their eyes, put their fingers in their ears, and say "la la la la I can't hear you," that doesn't mean the rest of the country has failed to propose reasonable solutions.
