Well, talking about those issues is just moral posturing without <power>, and politics is the negotiation of power.
These are all political issues. If you care about your fellow person, you already have the seeds of a <political> motivation. You want to change the way the world works -- but that takes power, power like the AMA or AARP has.
People who duck their heads in the sand and scorn politics and power as something dirty are counterproductive to this highly disorganized technical community with almost zero union potential.
I think technology coupled with a market economy shows us the way that societal transformation happens from the emergent order of individuals acting in their own self-interest, rather than being forced to choose a "better way" by those in power.
