If I'm not mistaken, "churchillbuff" is a woman. And as far as I know, "churchillbuff" is not qualified to talk down to a man who has spent his life serving his country when military issues are the topic. I guess we'll see, huh? I can't wait to hear why she thinks she can condescend to you on the subject.
