You really ought to take this to the politics subforum if you're going to address a hot topic like that. Personally, I think that's comparing apples and oranges when it comes to comic books, as I'm pretty sure "gay marriage" has nothing to do with the reason why comic book characters are not consistently married. Or why marriages get retconned so much as...

This. I really liked the Marvel "altverse" with Spider-Girl, American Dream and A-Next and the like, for this precise reason. What IF the characters aged? It makes it more interesting, and allows for a logical progression. Instead the aging is really random at best, and it just doesn't make for good story long term.

Admittedly, the 'singlefication' of characters is one thing that I found annoying about comics lately, though I think blaming "diversity" for it is a mistake. It's not like Peter Parker or Clark Kent started hanging out at gay bars... you've had numerous broken marriages in the past 5 years or so (either through the Devil or a reboot), and only one major gay character has come out as a result of the DC Reboot. (Batwoman was out back in the 52 series, I wouldn't count her, though frankly, she's far more 'major' right now than Alan Scott. If you consider Alan Scott 'major' anyway...)

(And technically, even though Vision was cussing out Scarlet Witch in AvX #0, he did refer to her as "his wife"... did the ink actually dry on their divorce?)

See, there's the problem - the OP limits the married couples listed to current universe couples in capes, while the gay & lesbians listed in the other thread were from all comics across the medium and also included pre-52 characters.

Marriages effectively ended by nu52 reboot (and not all of them):
Lois Lane and Clark Kent
Hourman and Liberty Belle
Barry Allan and Iris West
Wally West and Linda Park
Jay Garrick and Joan Garrick
Mr. Miracle and Big Barda

I'm not just talking the new 52 stuff. Marvel as well as DC has me annoyed on this issue. While I am reading my weekly books, almost every team highlights one or more of their characters in a LGTB relationship. While almost none today write of a marriage relationship. I will agree the New 52 has really thrown things for a loop. Destroying established marriages , while blossoming LGTB relationships, just for whatever reason. Still floored that Alan Scott Green Lantern is now written gay. For no reason the writers, threw away his long history, including his very popular offspring Obsidian and Jade. And for what? they had a Homosexual character in Obsidian. Again just don't get it. Why the lack of married superheroes for todays generation to look up to?

You're treating this as a zero-sum equation. It really isn't. Or at least, it shouldn't be.

Well I think this is a situation in which two premises are at work. Majority rules and Trendiness/Controversy.

Majority Rules: I would say that the majority of people who read comic books are not married. (Just for clarity, I have been happily married for 10 years.) So I think that they are not really interested in the marriage dynamic. They would rather see their hero hooking up all over the place because that is "cool". Marriage is viewed by many as a prison, holding people in the shackles of monogamy. I never really understood that, because as they say "the grass may be greener on the other side, but it still has to be mowed." I actually think realistic marriage protrayal in comics would be good for single people to read.

The other premise: Trendiness/Controversy: LGTB is clearly the new controversial topic in society today. In the past it was racism. Racism still exists, but it is no longer controversial to say "I am against racism" like it would have been in the 50s and 60s. So Comic companies thinnk they are taking a stand by pushing the alternative lifestyle to the forefront. I think it is okay for them to do this, just not with a character like Green Lantern, who was plainly heterosexual throughout his existence. That seems forced and no longer is a stance of support, but of propagation.

So in summary, Marriage is neither in the majority, nor is it controversial. Therefore, writers give it no value. That is a travesty in my opinion.

I think in one of the recent FF or Fantastic Four comics they were split. Crystal, though I dont recall if she wanted to or not, but she left ronan.

Matt Fraction & Kelly Sue Deconnick! oh you mean in comics, comics!

Well you all know why Sue Storm & MR. FANTASTIC have lasted right?

That times 10,000!!!! Both those books were at their peaks IMO when they were doing that. It gave us fresh takes on the characters

John and Epiphany Constantine.

Oops. Getting cancelled. See what happens when you get married. LOL!

Joking aside, Saturn Girl and Lightning Lad where mentioned earlier, but forgotten in the tally.
