Classical liberalism was about free thought.  

Modern liberalism seeks to restrict freedom.  They are all about freedom, except when it comes to guns, school choice, freedom of expression, health care, freedom of religion, taxes, etc.  They want women to have "access" to contraception and abortion, yet if the same women have cancer, they don't want them to have "access" to potential life saving drugs if those drugs are experimental.  Please, sir, don't tell me liberalism is about free thought or freedom.  Liberalism is about control. The funny thing is--guns are explicitly mentioned in the Constitution as a right, while abortion, health care, pot, etc are not mentioned! 

The rights that the Constitution explicitly mentions, liberals want to take away, while rights that are nowhere mentioned in the Constitution, liberals want to grant and claim they are constitutional!
