In fairness to Opal, the debate was less about Lily and more about why that guy was screaming at her every day solid for a month and accusing her of being a pedophile. Also in fairness to Opal, it's really hard to debate somebody else's points when they don't even know what you were talking about and are just exhibiting a constant knee-jerk reaction under ridiculous, blind assumptions. I don't think the conversation was ultimately fruitful, but it was a good microcosm for Lily's fanbase, who oftentimes don't bother looking at or acknowledging opposing points and just assume people hate Lily for being a strong Native transwoman lesbian.
An interesting thing that came out of that argument, though, is that the guy said he looked up the 'Stockholm TV Tropes page' and it basically portrayed Stockholm as a completely different story. It's not completely different, but it does happen to skim over the more disgusting parts of the story, skirts around the pedophilia, and does a curious amount of contextualizing and expositing. The YMMV page in particular has some interesting justification and explanation.
In fact, the tone of the article has a particular flavor, and is deeply specific for a relatively obscure fanfic series, and introduces some behind the scenes information that seems like it would be... difficult to come by.
Not that I would be suggesting that Lily made sure the write and curate the Stockholm page, the same way she definitely does not write and curate the Poke-Madhouse page.
(Seriously, go look at the Poke-Madohouse TV Tropes page. If it's not nakedly apparent that Lily is/was writing it herself, I'll buy a hat so I can eat it.)
Her deflecting this kind of harassment is especially interesting when she's previously said that it is a creator's responsibility to control their fanbase. She said that Josh Scorcher was responsible for the harassment she received after their falling out (despite Josh making a whole video telling people to please not go after her). She blames Rebecca Sugar for toxic aspects of the SU fandom. She blames people who make kid's cartoons for not somehow stopping lewd fanart.
But when Lily's fans go harass people? Eh, she can't be bothered to even make a gesture.
