I dislike it really a lot. I find it -- honestly, it's the double-standard that drives me up the wall. If non-explicit het subtext can be called gen, then non-explicit slash subtext can be called gen too. I tolerate slashgen better because, well, at least it's calling itself gen in there somewhere.

But it's probably relevant that I hate the usage of gen that is no-romance, myself. It's insane to argue that romantic human relationships don't, you know, happen all the time. If the focus isn't on the pairing, honestly, it's gen.

This is just me, though. I speak for no one but my own damned self.
