My opinion is that state and law should not care about sex of a parent or partner. Just to guarantee us all the same rights.
My other option is that this is quite bad news article (thou that might not be news site, so it is not on them, but on us) since there are a lot of opinions but is hard to find any facts in it.
What exactly is the law? Who exactly is who? What are the consequences, practical not only emotional? This is raising fear levels, but I am not certain what to fight against (except whole Italian government).
