Rightwing violence and US healthcare

An early morning line of thought...
The issue of firearms, rightwing violence (at least the implication) and Obama's healthcare is all over the news and blogs these days. It subsequently dawned on me this morning that every potentially violent divisive period in American history has a common macro-theme where one group of people at least in part feels that a disadvantaged population should be relieved of their burdens, be it slavery, being the subjectively wrong sort of Asian, or having no healthcare.

If we conceive culture as a complex and dynamic system of discourses, and analog this to broader complex and dynamic systems, like a human body, we can see how toxic patterns discourse might (re)emerge and disappear over time like a cancer. The symbolism and mythmaking (origin myths?) nurtured from the Revolutionary War onward produced some arguably very healthy socio-cultural cells, but also some utterly poisoness ones. Maybe the conflict-birth of that nation planted an adversarial and violent seed whereby anything that threatens certain (mis)perceptions of what ought to be or is, promotes a radical and violent pushback.

Perhaps part of this is the pathological adherence to rugged individualism and weapons by some segments of that society. To me this also implies a the hegemonic individual perception of a Hobbesian brutality to individual lives where the first response anything new is not to try to understand or discuss, but to resist with extreme paranoia. Particularly if it challenges the the very idea of that brutality. Is the rightwing blather about 'socialism' and the expressed racism of some, really about maintaining the old and carcinogenic discourse of violence?
