The level of condescending sentiment in that excerpt is repulsive.
Anyway, just because you attended a medical school in the US doesn't mean that will make you a better potential doctor than a smarter, brighter US-IMG. Hopefully, more and more program directors will recognize this.
Do you attend a US medical school? If you do, then you would know that many parts of the education are painstakingly standardized from school to school for good reason. Attending a US medical school guarantees exposure to this, thanks to the lovely LCME. I would rather work with someone who has core competencies than an unknown who studied a lot for the boards, then chose sketchy rotations nationwide and somehow got through.
As an aside, I don't think you can talk about condescending given your thread takeover of the anti-NRMP vent thread while "playing devil's advocate" (aka Monday morning quarterback) for the students who didn't match.
