Discord works absolutely fine in Linux. I use “Vesktop” which is a desktop client for Discord. Performance is identical to using the Discord app in Windows AFAIK.

I used to argue this stuff online. I had to quit for my sanity. If anyone wants a sample of the absolute insane beliefs and the staggering amount of handwaving these people are capable of, I suggest checking out evolutionfairytale.com. They will unironically claim to be objective, then a sentence later tell you that “proper science literature” is to be discredited because it has a pro-evolution bias. 🤣
