To elaborate on PD's point about left-handedness, we don't simply accept it, we accommodate it, through provision of special equipment (scissors, golf clubs, tin openers). My left handed daughter has the option of using both right handed equipment or left, depending on what suits her needs the most.
Our society now accommodates homosexuality, through marriage equality, cultural freedom and protection in law; it can only be hoped that one day every country will do the same.
