Guess what?  Someone has been messing with your mind.  They have been re-defining these words and then using the various meanings to confuse you.  If you are going to discuss these concepts, you first need to define these two words and then make sure that the person with whom you are having your discussion does not slyly shift the meanings of the words again.  

The term, Liberal, seems good.  It used to refer to people who reach into their own pockets to help those who need help.  Now, it means a person who believes in natural human righteousness.  Some of the side behaviors that seem to go along with the new liberalism is to take money from some people and give it to other people as a way to gain power.  Also, the new liberals tend to say that evil is good and goodness is evil.  They also tend to add to the Scripture and take from the Scripture--in they extreme, they replace the Bible completely with the carnal human mind.  The term, Progressive, is another related word.  Isn't it good to progress?  But most people who are what has been called Progressive since the late 1800s are really progressing against and away from God.
