Perhaps a little light...  

Maybe the rhetoric will flame out or just dull in the heat wave. Then we can talk about what the health reform law actually is doing and will do. An ordinary guy at Reddit plodded through the bill and came up with the best summary I have found.

Okay, explained like you're a five year-old (well, okay, maybe a bit older), without too much oversimplification, and (hopefully) without sounding too biased:
What people call "Obamacare" is actually the Patient Protection and Affordable Care Act. However, people were calling it "Obamacare" before everyone even hammered out what it would be. It's a term mostly used by people who don't like the PPACA, and it's become popularized in part because PPACA is a really long and awkward name, even when you turn it into an acronym like that.
Anyway, the PPACA made a bunch of new rules regarding health care, with the purpose of making health care more affordable for everyone. Opponents of the PPACA, on the other hand, feel that the rules it makes take away too many freedoms and force people (both individuals and businesses) to do things they shouldn't have to.
So what does it do? Well, here is everything, in the order of when it goes into effect (because some of it happens later than other parts of it): [Please read the succinct summary here]

Posting about the ACA is toxic, like climate change only meaner, and right now (drought) I really don't need that. Nor do rational arguments seem to gain much traction. Haidt's book made it clear to me why.

But I want to help readers when I can to at least be irate over real stuff, not pure lies. It isn't the biggest tax increase in history. People aren't dying because ACA has cut off their dialysis.

I don't want to add irritation to anyone right now, but a little light might help.
