"Liberalization" means many things, it seems, to different people. ;-) To me it means easing up on old rigid rules and providing greater freedom and greater latitude for free thinking.

The Catholic Church, for instance, has been greatly liberalized over the past many centuries, as have most of the other Christian churches. As a result, they are now more tolerant in a number of areas and women have a far greater voice in the community than used to be the case.
