Marriage is elastic

It's a carnival:

Three Brazilians in love have their nation up in arms over whether their relationship, now enshrined in a three-way marriage, is legal. The public notary who conducted their marriage says there's no reason the threesome – or "thruple", as the internet has charmingly labelled it – shouldn't enjoy the same kinds of rights imparted upon two people who get hitched.

Vox Popoli:

As I pointed out, correctly, once you start messing around with the nouns in "one man + one woman", you eliminate all the grounds for not messing around with the numbers too. Besides, the multiculti idiots have no choice but to support polygamy, since their precious third-worlders both practice and demand it.

Thus feminism dies, the victim of its own political success.

Victory has defeated them.
