I feel like I should say if you think you're "on my side" by saying genuine racist hateful things to black people in the fandom, then it is my personal belief that you should shoot yourself in the head with a gun.
I have met so many wonderful fans in-person at conventions. All of this toxic discourse we see on the internet regarding fandom are only a small portion of the overall fanbase, most of whom have been lovely.
Please strive to be kind. Thank you.
