Dallas’ Tincy Miller, a member of the State Board of Education, asked a perfectly reasonable question about some of Texas’s new social studies books. Why, she wanted to know, would they have deleted information about Christmas and Rosh Hashanah in favor of discussing other global holidays like “Diwali”? (Drawing a blank? It’s the Hindu Holiday of Lights.) When Miller called Diwali little-known and lacking much “substance” on KERA-FM, the arbiters of political correctness leaped quickly into action. The upshot: Miller has now apologized for her remarks. Even so, I doubt she’ll be on anybody’s Diwali-card list this year.
