Not sure that reply entirely matches with the statement. I can't see anyone advocating for complete removal of romance, but i don't see why everyone needs to be romanceable what's wrong with characters like Varric and Aveline? And what's wrong with having friendship paths of equal depth and connection? Especially if they occur simultaneously to a romance?
I usually edit my posts a lot. 
Anyway, it's not about not being able to romance everyone. If a character has their own reasons to refuse/not care about a romantic advance, then obviously it's not an issue to me. It's more about not being able to romance anyone for the sake of having no romances at all. My favorite relationships in DA2 were actually with Aveline and Carver, and although my canon relationship is with friendship romance Anders, I actually preferred the rivalry non-romance relationship.
As a gay male, I don't even play gay characters! I understand how it can be compelling to experience a second gay life (dunno if that's how I should frame it), but honestly, I'm just fine being a hot elven chick sleeping with Alistair, or anything that resembles him. If I want to have some "gay action", I could easily get it in real life 
Since we're "pretending" to be warriors, rogues, and mages while "pretending" to kill hundreds of mooks, I don't see the issue with "pretending" to get busy with people as well. It's all pretend. Let's not start with the "real life" talk please.
I'm pretty sure all of us have or will be sexual active IRL and don't need a video game to "get our game on". BioWare is relatively unique among RPGs in that it allows deep companion relationships to evolve into something more. What's the problem with that? It's not "second gay life". It's roleplaying a "gay character".
Also, just because I'm gay doesn't mean I only do gay relationships. It's nice to have the option.
