"4chan panic" is a reaction that'll happen no matter what. We laughed at the vanplosion and hacker on steroids report, but a lot of normies didn't know any better and took the fear as legit. Thanks to that and the general reputation of /b/ early on, perception as a whole's been in the toilet, and just updated now and then as new reasons to hate the place are invented.
There is absolutely no way to combat that. Haters are invested in hating, and for some people, just the fact that you can say nigger and not have your dog killed for it is enough. Not even that you(not you specifically but in general) actually might bother saying it - just the fact that it's allowed at all. Add homeconning gayops on top of that, and it's just not worth being defensive about.
All you can do is stuff like this, and the Exciting Updates staff puts on places like the reddit now and then. Talk about it normally like you are here, don't even get dragged into 4CHAN BAD derailments. The more moderate and non-psycho types respond to what looks interesting. Lots of new shiny shit and people having fun is interesting. Arguing with jackasses is not.
