What people do in their own homes in their business. As long as all parties are consensual and no children are involved with anything sexual, what business is it of anyone else? You couldn't stop 3 or more people from having a relationship, so why stop them from marrying? If there's some sort of scam involved that would hurt taxpayers or anything like that, then it would be worth looking into. But if the criticism is just based on social standards, it's stupid.

"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
