I had a battery clerk in Vietnam who was, if not actually "openly" gay, at least well known to be. He was a crappy clerk, but that had nothing at all to do with his sexual orientation. Officially ending "don't ask, don't tell" will enable those who are mistreated by their peers and superiors because of what is "unofficially" known to begin making official complaints and to have the boom lowered on the perps just as it is in any other case of sexual harassment.
