Thanks for all the great advice. It looks like I probably won't be taking him along, for most of the reasons already mentioned.
This has been an issue over the past year, as I have felt uncomfortable bringing him to dinner's at attendings' homes and other med school social events. I'm out to my class, but didn't want to risk making an attending who will be grading me uncomfortable.
Understandably, my partner feels left out and it causes tension between us when this happens.If I were straight though, I would totally bring my SO to the pre interview dinners. This person is going to move to a new city with you; which they won't know until match week. In the past, I have seen that residents and applicants SOs were able to talk about the job market in the city, living expenses, social/cultural events, etc.
I think it is easy to oversimplify these situations online, so I begin many of my messages with the comment that I don't know all the specific details about your particular situation, and you should probably take my advice in with the same regard as you would a physician offering clinical advice over the phone... i.e. with a grain of salt.
-- If you have decided against taking your "SO" to the dinner because he would not find it a useful experience, I think that is an appropriate concern (although as you point out, not always the case).
-- If you have decided against taking your "SO" because you think having a partner would somehow put you at a disadvantage in the application process, I personally think that is probably a ridiculous assertion, but fine... also an acceptable reason.
-- But if anyone is not willing in this day and age to bring a SO/partner/spouse along to a social function in the medical field simply because you are both of the same sex, then shame on you! Go watch the Harvey Milk movie or something...
I'm not going to lie and say there aren't aspects of the medical field that run rampant with homophobia, but consider the opportunity costs involved when you go to such great lengths to maintain the illusion of heterosexuality (throughout the interview process and possibly even residency). Obviously, this sort of stuff happens all the time -- It is inexcusable, especially as it begins to infect the physician-patient relationship -- as a doctor projects his or her insecurities onto patients and colleagues -- thus, limiting access to care.
Granted, this is a complicated issue, and I would never advocate for someone to go out and grab their glittery pink feather boa and prance through the OR looking like a cheap ***** (don't think I haven't seen it done before), and I certainly think it would be inappropriate for you to go around "flaunting your sexuality" around the other applicants and residents with disgusting/loving glances across the table... (you don't want to make anyone sick...) but we all have a responsibility to help people (including PDs) find the value in diversity in medicine (with regard to age, religion, race, sex, gender, marital status, sexual orientation, disability status, etc, etc). You will find physicains who disagree with that statement, but they have absolutely no value as humans, and most of them will likely die off in the next 10-20 years.
Believe it or not, I've even found surgeons in Texas and Utah (in addition to California, New York, Massachusetts, etc etc) who celebrate the idea of having "the gays" on their staff... and I think that as long as you stay away from the old curmudgeons in Florida, you will be just fine and you will match and you will be happy where you end up and you will be grateful that you didn't sell your soul to score yourself a better job. If, for one reason or another, you decide to completely throw your partner underneath the bus on behalf of your career, that might be something important to acknowledge to your partner so that he or she may consider it in his or her decision to completely uproot his or her life and move across the country on your behalf.
If the AMA is able to vote as a national body (even with those nasty ortho surgeons on board) saying that transgender patients deserve access to appropriate treatments prescribed by their physicians, then I'm sure a similar body of physicians involved throughout the interview process can get on board with the fact that there are actually one or two competent physicians out there who also happen to be gay...
