Let's start over.
Do you think that AAMC should implement a "don't ask, don't tell" policy? If so, why?
Right now, no one is asked to disclose sexual orientation on the AMCAS application and no one is forbidden from mentioning it in a personal statement or secondary (it's not asked but you can tell). Should the policy change to forbid mentions of sexual orientation in the personal statement and secondary? What would the justification for prohibiting such a disclosure?
I'm heterosexual. I've been examined by dozens of physicians in my lifetime. I never asked if any were gay and none ever told me that they were. I was not there on a date and I don't think I'd have cared if a physician who was doing her job by examining me was a lesbian. If a male physician was gay, it would not matter to me.
Some gay and lesbian individuals feel misunderstood and mistreated by physicians who are insensitive. Many of them welcome the opportunity to be cared for by a gay-friendly physician. In some cities there are clinics specifically geared to the needes of that community. Some medical schools are glad to have gay-friendly medical students enrolled because these students are future providers of care to an otherwise marginalized segment of society.
