Some really good points (and plenty of bad ones) on this thread. Let me start by saying I graduate from an Osteopathic school in a couple weeks, then I'm off to an Osteopathic residency, and I applied to only Osteopathic programs during the process. Sorry, I just don't want what I say next to be misconstrued.
I say this DO2MD thing is a good thing. What? Blasphemy you say? I say it's good because I'VE EARNED MY DEGREE! I've earned the right to carry the letters D.O. after my name. And all these fools want to change MY DEGREE? And I agree is is mostly pre-med and osteopathic medical students pushing for this thing, even though there are some physicians agreeing to it as well. And it was stated before, you want an M.D., you should have gone to an allopathic school. Don't change my letters because of your own selfish agenda. You want to be an M.D., but went to an Osteopathic school, use this website, but leave my degree alone.
And next year, I'm gonna be the John Hancock of the Osteopathic world, and sign my letters in size 72 font. That's how proud I am of what I've earned.
