By the time most people are adults, they're mature enough to realize that every choice we make has some sort of consequences. They may occur prior to getting what we want, or they might follow it; they may be good consequences, or they may be bad. Then there are those who never seem to reach that maturity. They're stuck in the childish dream of wanting their choices to be free from any limitations, unable to accept that their choices may have consequences or that there may be some manner of prerequisite before they can have their choice fulfilled.
We can see this in action in the anti-vaccine movement, in particular as they fight against a bill in California (SB277).
