You have it backwards. They can't stop gay people from marrying, no matter how much they stamp their club feet or how long they hold their stinking breath.
Actually, a state can stop gays from marrying..
No more than a state can stop a mixed race couple from marrying
Which is why in all 50 states it is legal for mixed race couples- and gay couples to marry- despite State's objections.
And why it should be legal for a woman to marry the entire Dallas Cowboy team, if she so chooses.

So you are in favor of polygamous marriage- thank you for once taking a stand on behalf of that poor woman and the entire Dallas Cowboy team.
Now all they have to do is do what the Lovings and the Obergefell's did- go to the court and claim that their Constitutional rights have been violated and that they should be able to be married.
Like the Lovings and the Obergefells they have to make their case- and the State has to come up with a compelling reason why the State law against polygamous marriage should stand.
BUT if the State can't come up with a valid reason why bans on polygamous marriages are good- then why does the State even have the bans?
You could start the ball rolling tomorrow- by going to court claiming your right to marry 3 women or 3 men is being denied- go for it.
