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.
If they excessively quote the original letter in their reply, it’s not real. Nobody puts this amount of effort into a rejection when they are obviously being mocked by the sender. They would send a generic “not what we’re looking for” rejection letter at most.
