The irony is that conservatives believe in a flawed man who should be left to fend on his own; i.e., given individual liberty; while the liberal purports to believe in a perfectible man who requires lots of governmental meddling since he apparently shouldn’t be trusted to make his own decisions.
The even greater irony is that liberals believe people aren’t able to make their own decisions, but somehow there is a special group of people who can make not only their own decisions but also everybody else’s.
