Where to begin!
First off, I don't like the New 52 and I'm not reading any of it, but... I really never thought Batwoman lived up to the hype. I tried it. I tried it longer than anything else in the NuDCU. I even checked out the trades. But Williams just isn't much of a writer. Frankly, as much as I hate to come down on the same side as Didio, I think the series could use a fresh approach.
Secondly, none of the Bat-characters marry. Their life is the job (and seeking Batman's approval). Not the healthiest of lives, but I wouldn't want Batwoman to marry. And I don't have a problem with comic characters marrying. I think the Parker and Kent marriages should still be canon, but, again, I don't want to see a Batwoman marriage.
Third, its called 'married,' not 'gay married.'
Finally, I don't think cutting all your DC titles from your pull lists is going to hurt retailers. I am buying more monthlies than I have in a long time, and Hawkeye is the only one from the Big Two.
