There is a lot of value in calling a spade a spade because far too many people have been enticed by the fascist left because they call themselves liberal, and many people consider liberalness (in its true definition) a virtue and something to be admired. They're seduced by false advertising.
I understand and sympathize with your point, but the fact remains that if you call yourself a liberal, most people who don't yet know what you really mean will assume that you are much closer to Hillary Clinton than Thomas Jefferson. That's okay, of course, if you are willing to take the necessary time and effort to clarify what you really meant.
