Nothing to pardon! Liberalism is the philosophy in which individual equality before the law and inalienable liberties are the top priority.
This can fit in well with democracy (e.g. Bill of Rights), but can also be absent in democracies (e.g. the majority being able to vote to kill you). Similarly, liberalism can influence governments of all types, codifying individual rights and laws which can limit the power (or at least the rights) of the government.
