I don't see what is "yuck" about it. I mean, I am not gay in the slightest, and personally, I find the whole concept repulsive, but why do you care who sleeps with whom, and who marries whom? I mean, if a dude wants to marry his lawn chair, and said chair is adult and sentient, and can consent, what concern is it of yours? It's not like they are forcing the Churches, Synagogues, Temples, or other religious facilities to perform such marriages.
I think its nasty, personally. But it also doesn't affect my marriage. Does it affect yours? Are you and your wife threatened by what two men do in their bedroom? If you are, I would say you have some VERY serious issues, man.
EDIT: Just for informational purposes, right now I am on my computer, but some times I shall be on my basic phone when I respond. When you see a response that uses abbreviations (such as w/ or @) and a lot of contractions, and is very short and terminates in a (CONT), that means that I am on my basic phone and out of space, and indicates that I shall be following up with another post or more than one. Please be patient and do await my response. I am quick with a phone keypad at thumb-texting my responses, but not as quick as a full keyboard, obviously. Thank you for your patience.
