The push for ‘homosexual civil unions’ is just another way of saying “homosexual marriage”.
You do understand that, right?
It doesn’t mean what you think it means.
It is a typical propaganda move, use terms in an incorrect fashion to mask intent.
Besides, they can write a will just lie anyone else as someone else mentioned above.
And even if it's not saying it now, it will be in five years. Just ask anyone over the age of 40 about the changes they've seen in politics and the culture that they never, when they were 20, thought they would have seen. I think you have to be either very young or very naive to not see the camel's nose under the tent in such matters.
