I've no doubt that things would change in a positive way. Don't get me wrong but you're a tad bit of a cynical person.
I don't know the reason behind, but you've been consistently sounding in hundreds of your posts in countless threads on SDN like that you embraced your URM status just to gain passage to the "glorious" MD world territory, but unfortunately like that didn't understand the meaning behind why this favor was done to you.. It was because US should embrace the diversity especially in public service, such as medicine.
There've been many turning points in modern US history. Likewise, I see this MD & DO unification process as a goodwill as well as a must that come from both sides for getting to something better for the patients; this is something like the civil rights movement in the US.
As the physicians, we should embrace all practically available methods to heal the patients without risking their lives. So, cleanse your pre-med hatred (or whatever you have in your blood), and wait and see the change.
It stands too controversial to convert 320,000 foreign med school graduates into MD but to exclude the DOs from the pack... Thus, I don't agree with you in that any PD would discriminate any DO that has sufficient scores from COMLEX or USMLE, come 2015.
