What is it modern liberals say again?

Something to the effect that all cultural norms and standards are equally valid and that no culture's norms and standards should be judged by another culture's norms and standards?

The Vatican on Sunday raised the possibility of using behind-the-scenes diplomacy to try to spare the life of an Iranian widow sentenced to be stoned for adultery.

Talking to Sabra the other day, I observed how ironic it was that the feminist movement is still so overwhelmingly liberal, considering modern liberals' attitudes towards phenomena such as multiculturalism and cultural relativism -- that is, that they would be aligned with such an ideology considering certain cultures' attitudes toward females. I did this on the heels of telling her about something I saw at work -- a little Mexican boy, couldn't have been any more than about six years old, telling his slightly older sister, "Fuck you!" and his mother not doing anything about it. Sabra had mentioned before to me that the Mexican culture values boys much more than girls, or something to that effect. Because of that, in the Mexican culture males can get away with all sorts of behavior toward females (such as what was mentioned above) at which American feminists would rightly be aghast. Yet said feminists align themselves with an ideology that will tolerate this just because it's another culture's standard. The first comment I saw this story was this:

NOW organization strangely quiet about treatment of women in the Muslim world. Why is that? Is it because they hope Muslims will vote for Democrats?
..
Anti-War Moms are strangely quiet about the escalation of the Afghan war. Why is that? Is it because a Democrat President did it?
..
Can we conclude that issues of life and death take second place to power and money with the Left?

It certainly seems that way, doesn't it?
