You can't really do a comedy blog if you're worried that making jokes and satirical cultural observations might offend people.
I'd like to note that I've done just as much satire on Americans as well, including a post just today about how Americans are basically brain-damaged uber-violent maniacs (thanks to dodgeball).
I guess I'm fated to be hated on both sides of the pond. 
This has been an interesting discussion to me, since I've greatly enjoyed your satirical blogs and so has my British fiance. This Thanksgiving one was also very funny, but I did have the feeling that it skirted (and every so often toppled over) the line toward anti-British. Since I've read the others, and your posts on UK-Yankee, I know this was just one of those times when my sensibilities were tweaked, but not in any way an indication of your feelings toward Americans or Brits.
How anyone could possibly write satirical commentary on social issues and
not tweak the occasional sensibility, I have no idea. IMHO it should just be considered a risk of the trade and a learning experience when tweaking occurs. This opinion, of course, is mine and may have nothing to do with reality as I've never attempted a satirical blog post....
... but I'm very happy that you do make the effort and I happily reap the benefits with a well needed laugh now and again.

By the way, your post on dodgeball was absolutely spot-on! I think you may be on to something there, and, as the quite often last picked team member in elementary school games of dodgeball and other sadistic school sports, I salute your skill with words!
.... after I have a mini break down over traumatic childhood memories anyway....
