I don't know, all I know is that it takes time. We still have political party's that exclude gays and women and this is probably the most gay-friendly country.How many more 16 year olds are going to miss out on a normal, happy life until that other 49.9% figure out that they are children just like all the others, not spawns of Satan? These are real people being ostracized for something as unchangeable as eye color, not some abstract political debate.
