This is mild compared to the vitriol of some Facebook groups.
I had to leave the Star Trek Continues group for my own well being. Its members, despite empty warnings, just attack Discovery and anything else new, while sending up hokey memorial threads to minor personas who had some connection to TOS and pushed up their last daisy years ago, with a lot of creepy idolizing of Michele Specht to fill out the whole thing.
If there's any made up controversy to Discovery, they're on it like a fly on a turd, though strangely silent on a certain STC founder's own current troubles.
