Old_Geezer //Bible or no bible, the definition of marriage concerns two genders. //
That is just your preconception. But you would be alone.
In fact, in Australia, a few years ago the legal definition was changed because it originally never mentioned two genders and the government of the day wanted to prevent same sex marriage. It was done by a simple act of parliament.
Now that most Australians support same sex marriage, while the conservative wing of the government vehemently opposes it, their policy is for a plebiscite, "because everyone should have their say".
Funny how they don't ask the people about many other things we would like to "have a say" on.
