IMO, Bloodborne is an almost perfect game, design-wise. But I just wish it didn't have chromatic aberration. I hate it in every game and the fact that one of my favorite games has this shit built in and you can't turn it off will always bother me.
Also the performance is horrible but I don't think many people would disagree with me on that.
This was definitely a 4Chan thing. I frequented that pisshole quite regularly around that time, and the LGBTQ+-hate was a prevalent stance when it came to characters in videogames. And since they have a history of brigading and manipulating "contests" like this, I would be very comfortable in mostly attributing this to 4Chan. I remember plenty of threads about this from back then.
"Right-wing organization" would not be the right term here exactly. 4Chan themselves would likely call it along the lines of "weaponized autism". In less inflammatory terms, they did it because they were bored, they had the time, and simply because they could. This particular case just "happened" to be about their anti-LGBTQ+-stance. A lot of their actions tended to have that particular flavor.
Sickening place. Glad to have left it for good years ago.
