I had a milk related topic not too long ago that addressed part of the extension. 1940's bullshit legislation that forces the government to buy milk is bullshit legislation. Not getting into the details all over again.
The farm bill doesn't just make the government buy milk just look at page 5 of the dang link and it covers everything the bill covers. If you still think that's bullshit, then okedoke, but at least know the whole story first.
