One hundred years ago, chinese people were not allowed to vote in Canada, nor were native amerindians. Now All races are considered as legal persons.
In 1931, the British House of Lords determined, in an appeal of a prior Canadian Supreme Court rejection of women as "persons" that women are indeed, legal persons and equal to men in law.

And now homosexuals are fully legal persons, that have the right to marry.
My advice to those who disagree: Do you really want to be categorized along with racists and other bigots?
