A world-wide consortium agrees to build escape vehicles, so a small group, of all races and creeds, could go out into space to colonize other planets that could support humans. From a group of several thousand candidates, scientifically chosen, the vehicles could only accommodate 300 persons. The selection of colonists would be based on mathematical criteria for the greatest chances for survival of the human race.
Would the scientists be called "bigots," if they considered a candidate's homosexual identity, as a social negative---a disqualifying characteristic for colonists needed to re-populate a planet?
Would they choose 300 homosexuals--300 negative procreators?
Would they choose even one negative procreator?
Society has always condemned anti-social behavior--behavior that is opposed to the natural social order. Behavior, which, if multiplied over the total population, threatens the harmony of, or existence of, society, is negative behavior.
Equating racial discrimination with my civil right to reject someone's negative behavior is the real bigotry. One's "preference"--choice--of sexual behavior, has nothing to do with one's race, which is not a choice.
