Remember, this is the kind of Cuckery and shitlib garbage that sank the first #GamerGate. Be on the lookout for SJW Lites and cucks, never tolerate fags like that, treat them like Lolcows or Enemies, and NEVER let them call the shots. #GamerGate2
I'm a little late to this, but I feel the need to mention it because I feel like these people are just going to move to Telegram, if they already haven't.
Telegram is NOT a better alternative to Discord. It asks for your phone number (huge red flag), lies about being end-to-end encrypted (encryption is done server-side), is centralized, and not entirely FOSS (server-side software is closed source). Look into decentralized/self-hosted solutions instead.
I personally recommend hosting an XMPP server. Install an XMPP server stack that supports multi-user-chats and host your discussions there. With XMPP, you can sign up for an account on any server and talk to anyone, including people from other servers. There are even modernized web-clients like Movim which make it more user friendly.
For private/direct messages, you can also end-to-end encrypt them using OMEMO. Just don't use them for public MUCs or you will end up having problems. You really don't need to encrypt a public chat anyway.
If you need help running an XMPP server, Mental Outlaw made a video on it.
But I was rubbernecking this nonsense from the start, and it was obvious right from day one that #gamergate was a way for corrupt corporate shills to deflect from their own corruption by trying to shift the blame to someone/everyone else. Part of the reason I caught on so quick was that I'd seen the exact same pattern over and over again previously in the left-wing activist milieu (eg. Occupy movement).
My assessment now is that most of the folks involved in proclaiming the "gamers are racist/sexist/bigots" narrative, had/have all the classic signs of narcissistic personality disorder. Their ability to organise a lynch mob under false pretences has discredited everything they stand for in my eyes. Even when I agree with them, I won't make common cause with these people for that reason.
