They can get married if they want, but as with anything in life, there are parameters:
No inanimate objects
No animals
No vegetables
No children
No siblings
No person with the same equipment
Well, that's the definition of marriage. isn't it? Always has been, always will be, even if the Satanist Commies try to bastardize it. Seems to me the homos have three choices...either 1) give up their homosexual ways and go straight, in which case they can find someone of the opposite sex and get married, 2) find a beard and marry him/her/it, or 3) STFU and accept the fact that they're homos and can't get married. They made their bed, now they can have great, big, homo baby oil parties in it.
Of course, they won't choose any of the three, instead screaming like a bunch of little biyatches and forcing their aberrant and disgusting lifestyle on the rest of us. Unless, of course, we the majority find our spines and stand our ground...pun intended.
