The online Oxford Dictionary defines “liberal” as:

“Willing to respect or accept behaviour or opinions different from one’s own; open to new ideas” and “favouring individual liberty, free trade, and moderate political and social reform.”

In the U.S., “liberalism” has increasingly come to mean just the opposite of this definition.  American liberals and progressives are neither liberal nor progressive.  A term that more accurately captures their political beliefs is the “Left,” defined by Oxford as “[r]elating to a person or group favouring radical, reforming, or socialist views.”  The American Left is authoritarian (favoring strict obedience to authority at the expense of personal freedom; showing a lack of concern for the wishes or opinions of others), intolerant, and illiberal.  So stop calling the Left (or yourselves) liberal.
