Let's all remember that the main culprit here is bigotry and how it is normalized in gaming spaces, and how it's a reactionary outburst against minority representation in AAA gaming. Even if Jim didn't exist, I fully expect Druckmann and ND would receive similar amounts of vitriol.
The bigoted fucks Neil is calling out in the OP are either still convinced Abby is trans... or are continuing to spread those fake spoilers because they're much easier for the bigots to weaponize, than the real spoilers related to the game's actual trans character Lev. Probably a mixture of both, honestly.
That should tell you all you need to know in regards to whether Jim not making a video would have made any real difference in the end. And while I do hope and trust that he will call them out for this shit in a future video (as he has done so many times before), he does not deserve the blame for the disgusting shit in the OP.
