LGBTQIA, sometimes LGBTQ, sometimes just LGBT.
Mostly, just G.
I swear, it's not a week anymore if I'm not stumbling across some new review site or publishing company or website or blog that touts how much it supports the LGBTQ community and how they're great allies…
… only to read further and find that by LGBTQ community, they mean the M/M community. That they'll only review M/M books because well, they don't have any reviewers on staff who want to read lesbian romance or romance with trans characters (and heaven forbid if you lob a curveball and throw an asexual romance or 'worse' at them). Or they'll say LGBTQ, but if you look through their site, you'll find nothing but reviews of M/M books.
That, by publishing LGBTQ romance (wait, wait, I've got this wrong, G LBTQ romance, there we go), they mean they publish M/M. And yes, I know that's where the big sales are. I run a publishing company and I'm heavily involved in the finances of said company. M/M romance does very well for itself. I've also seen lesbian romance do very well for itself (some of LT3's best sellers in 2014 were lesbian books).
Trans and other queer books don't sell well.  
Because on the whole, (1) readers don't buy them, (2) reviewers won't read them, (3) writers won't write them, and (4) publishers won't publish them. (Obviously there are exceptions. But on the whole, this is true.) There are queer books out there (sometimes they're hard to find, though that will hopefully be less of a problem in the near future when Amazon revamps their categories). There's fewer of them than there are M/M romances, but they are there. That they don't sell, however, is not the point of this post.
I'm sure you're wondering, well, what the fuck is the point of this post, then?
The point of this post is that these books deserve the same treatment as M/M romance books. They don't get it. They don't get it, and I'm fed up with reviewers, readers, writers, and publishers who pull themselves up on high pedestals and trumpet their liberal viewpoints to the world. They're diverse! They're allies! They support the LGBTQ community!
Except, here's a novel concept: You do not get to call yourself a supporter of or ally to a broad and diverse community because you like and focus on one specific segment of that community. Full stop.
(Related: you do not get to call yourself an ally in your own defense when a marginalized person is telling you that you're being a bigot. I don't give any fucks about your self-appointed allyship. Your Ally Card is currently being burned in effigy.)
If you want to be an ally, you cannot limit yourself to simply M/M romance. That's just not good enough. I don't begrudge anyone a preference for M/M romance. I do begrudge people claiming that they support the LGBTQ community, but who then follow that up by doing nothing for the L, B, T, or Q (or I, or A).
I'm not the best writer when it comes to diversity in my fiction. The majority of my books feature bisexual romance (*). It's a problem I'm actively working on. I want to write more lesbian romance. I want to write asexual romance. I want to write more trans romance. I will write these books, because it's important, because supporting the entire community is important.
(*Most of these books pass as gay romance since two cisgender men end up together at the end, but I pretty much always write my characters as bisexual. It only occurred to me recently that people would read that wrong, so I'm getting better at explicitly saying so in-book.)
The point of this post? To issue a challenge to you. Step up. Give something other than an M/M romance a chance. At some point you gave an M/M book a shot and fell in love with that genre. What's stopping you from giving that same chance to a lesbian or trans or other queer book?
