[I]f we have learned anything from the significant evolution in the prevailing societal views and official policies toward members of minority races and toward women over the past half-century, it is that even the most familiar and generally accepted of social practices and traditions often mask unfairness and inequality that frequently is not recognized or appreciated by those not directly harmed by those practices or traditions. It is instructive to recall in this regard that the traditional, well-established legal rules and practices of our not-so-distant past (1) barred interracial marriage, (2) upheld the routine exclusion of women from many occupations and official duties, and (3) considered the relegation of racial minorities to separate and assertedly equivalent public facilities and institutions as constitutionally equal treatment.

And that, right there, is the heart of all of this. Everything is “tradition” until we realize it needs to change.
