Political Correctness Overload Alert
I had no argument with his points. They were reasonable. I do take exception to him poking fun at gay couples for their flamboyance in order to make his point. That is pretty weak, easy, and obnoxious material based on old stereotypes that are hurtful in the wrong hands (and by "wrong hands" I mean some people who are probably in Keillor's fan base and do not live in areas with many openly gay citizens. These people vote. These people make decisions about gay marriage.).
Maplewood has a large gay population...parents who have left the city to raise their kids. NONE of the gay couples we hang out with are "flamboyant" in any way (that is not to say that flamboyance is a bad thing - which it is not - but simply that Keillor does not know what he's talking about). They're just parents doing the job of parenting just like anyone else in town. If I want "humor" like this, I can listen to a Robin Williams or Eddie Murphy bit from the 80's. I always thought Keillor was known for his dry wit. I see neither dryness not wit in this writing at all.
By the way, you may recall that I returned my tickets to see A Prairie Home Companion live in New York. I sent them to Keillor with a note saying that I was pretty annoyed with his Christmas article and therefore did not want to see his show. I have not heard back from anyone associated with Keillor. Not that I expected one, but it is worth noting.
