There is no such thing as a value-free concept of deviance; to say homosexuals are deviant because they are a statistical minority is, in practice, to stigmatize them. Nuns are rarely classed as deviants for the same reason, although if they obey their vows they clearly differ very significantly from the great majority of people.
