The sequester was the result of the budget supercommittee failing to reach a deal, which then would have gone to a straight up/down vote in the congress. The committee was 6 Democrats and 6 Republicans. The blame for not coming to an agreement rests equally on both sides. (And keep in mind that any argument you make that D's were saints and R's just wanted to sink it would would be just as arbitrary if you exchange 'D' and 'R'.)
Also, Obamacare isn't part of the sequester because its full funding is provided for in the PPACA.
On top of all of that, Obamacare doesn't even pretend address the entire lack of a responsible mental health system in this country; that's not what it's about. It would only address insurance coverage for it if we even had something approaching a mental health system.
So not only does Obamacare have nothing to do with the lack of mental health treatment in the US, but Obamacare wasn't even part of the sequester cuts, and the cuts themselves weren't some vast right wing conspiracy. You're 0/3.
So back to my original questions:
1. Can you sight a case of right-wingers cutting social services, causing mentally ill people to be loose on the streets?
2. And do you have any comment or refutation of the ACLU's decades of lawsuits against the mental health system we used to have being the prime reason it no longer exists?
