No it's common sense. If you are calling me a Nazi, this I wouldn't recommend.
I have colleagues where I teach who are gay or lesbian. They are some of our best teachers and scholars at my university. There is never any indication that their treatment of students is inappropriate or unprofessional. They live quiet lives; certain of them have been in decades-long monogamous relationships. They do not deserve to be excluded from their profession simply because they are gay. Nobody chooses to be gay (not knowingly), but they do choose how they live. I have nothing against gay people who live quiet, responsible lives. They shouldn't be excluded from professions on that basis.
