I think that you might want to have a plan in place for the time that you decide to come out to your family (or for the time that they find out before you tell them). As much as you hate being labelled, you cannot stop them from labeling you if that is what they decide to do. Given what you said about their views on homosexuality, I am sorry to say that it sounds like there is a good chance that they are going to label you once they know. My advice is to be prepared in case this does happen.
