When I read this thread for the first time, I saw Colin and his usual display of disregard for all things American. So then I ignored it for a while, but then it occurred to me.
Colin, who gives a flamin' friggin' fart about touching or not touching the Queen. She's human, born of woman, and isn't elevated 90 degrees towards divinity. When she dies, she's gonna moulder in her grave just like John Brown's body. So if Michelle Obama wanted to touch the old biddy in an affectionate way while she was still alive, what's it to you? A sign of disrespect, perhaps? Akin to the disrespect you've shown Americans on so many past occasions. Perhaps Michelle knew it would bother you, so she did it for the pure spite of the moment. But you wouldn't know about spiteful moments, would you? No, I didn't think so...
