Good question. In one modern use it is someone who, despite evidence to the contrary, believes everyone has good intention(except the opposition) and that no one is gaming the system leeching off the hard work of others. Heck, even if they did allow some of those thoughts to drift through their indoctrinated mind they would dismiss it saying the end justifies the means(like a sociopath would). One can usually sniff out a liberal by reading their posts. I hope this helps. Tomorrow we can go over the difference between forks and spoons.
