I hardly think it's "sizable" anymore. After all, you are all responding to one poster here.
I think, early on, some people (self included) were willing to consider that Nick was cajoling her into stuff. I think these people were giving her the benefit of the doubt, and applying some reasonable objectivity, because we know way more about him than her.
Further mudding the issue were things like Nick's "body destroyed" rant (which earned her a fair amount of sympathy), the fact that Faran's story has some big issues, and the fact that TiC kept posting that "bug eyes" crap to the point where I think people got genuinely sick of it.
Fast forward to now, and I don't think most people see her as so innocent anymore. If she's not actively enabling this shit, she's at least passively doing so. This shit has been going on for far too long now for her to not bear some responsibly. In addition to what everybody else has already pointed out, I think the biggest dig against her is she is his wife, and yet she seemingly does nothing as he self destructs. You know all the people here pondering why nobody has tried to stage an intervention? Well, she'd be a good candidate to lead it. Perhaps the best.
Plus, Nick is such a disingenuous faggot, he'll whine about people "attacking his family" even as nobody is actually attacking his family. Remember Claire? She vigorously defended his wife, and Nick still shit on her for criticizing him in the course of doing so. He was positively giddy when she and her family (which includes children younger than his) were victims of multiple crimes.
So, in conclusion, fuck 'em both.
