It is not bigotry. Homosexuality is a behavior. It is not the same as skin color, being left handed, blue eyes or brown hair. There is no bigotry involved in being honest about a deviant behavior. Homosexuality is a deviant sexual behavior.
Look up the definition. The act or state of being utterly intolerant of any creed, belief, or opinion that differs from one’s own. You said ALL homosexuals are promiscuous, disease ridden, etc. That is patently false and unfair, but if you don’t want it to be described as bigoted, I guess we can go with ignorant. There are plenty of promiscuous, disease ridden, immoral, amoral, heterosexual deviants serving in the military. Do you object to them? If homosexuals want to serve my nation in the military and serve honorably, they will have my thanks and admiration regardless of what they may do in private as long as it doesn’t effect me or mine.
Being monogamous with only one opposite sex partner in a lifetime is deviant sexual behavior, just so you know.
