Not everyone on BLF has/wants Discord, so you'd be splitting the sub-community that the discussion topics have created
not really, the discussion topic "community" consistently mainly of like 6 or 7 different people, all of which most likely have discord. there's no actual reason to intentionally not download discord; so if they are too up their own ass to do so then it's their fault.
that argument only works when you're talking about giant groups of people
