I am sorry if modern secular Western culture presents those values in a greater degree than others. And by the way, you may have noticed that whenever people are allowed to think for themselves for a significant period of time, they embrace Western values and demand Western-style institutions. With respect to Michele's message board, I would rather comment on the items she proposes here. I am not an education expert, but if you are referring to the California brouhaha, it seems pretty obvious that bilingual education was a mistake from a pedagogic point of view. It's time to get over it and try something better for Latino children, as opposed to PC activists.
Discrimination regarding age per se is bad.
But some relevant characteristics in life, such as physical health, openness to innovation and looks are strongly correlated with age. Ditto for the handicapped. It is probably wrong in most cases, but the solution must come from individuals themselves, not by PC censorship. When this kind of behavior is shown by racists I call it paranoia. Just like racism.
