Its simpler to define it with one or two examples of liberalism.
1. Hate crimes. That a crime is not only a crime but a more severe crime if it is targeted at a group or individual in a minority. Ie If a Black is killed by a white man just because he is balck it is a worse crime than if a balck man killed another black man because he was black.

2. Abortion. That it is OK to kill another human in order to protect ones rights over her own body. Yet if you kill a woman with that same baby in her womb it's two counts of murder. While also asserting that the father whom donated half of the genetic material for that baby has no rights until the baby is born but is always financially liable for the child. Then on top of allof that it is ok to harvest tissue from the dead baby for the greater good of man because it was dead anyhow.

Those mind benders are great examples of liberal thinking.
