> We have made huge progress in areas such as women's rights.

In the U.S. there is still a major fight for women's reproductive rights, with frequent backsliding (TX is the most extreme recent example).

> All of this progress has occurred without any of the radical discrimatory tactics that are used today.

Every step toward restoring human rights to marginalized groups has been labeled radical (because technically it is radical compared to the status quo) and must come at the expense of some privilege that others hold. Privilege, however, is not a human right and therefore not something inherently worthy of protection.
