That is probably true, and it is practiced perfectly by the 'rats. The rats will take what they can get and keep chipping away
Unfortunately, the GOPe does not practice this sort of incrementalism. Their idea of incrementalism at best is to stall the 'rats in the implementation of their agenda. It's the way the Cold War was fought before Reagan when most believed the Soviets were winning the Cold War and the best we could do was stall or contain them.
All we have seen under the GOPe is that our rights are gradually eroded away, rather than taken in one fell swoop.

Well, I don’t know about you, but my parents were never lying, selfish, back stabbing bastards and they didn’t hate me and give all my stuff to kids down the street.
