I know one of the people listed; and she is indeed a nutcase.
It will be interesting to see if meetup.com persists in pushing this crap or if today's attack shames them into taking these groups down. (For those who aren't familiar with this: Meetup.com groups are normally created by the officers of local clubs; and meetup.com just provides the website/IT infrastructure. These #Resist groups, on the other hand, are being created by the company.)
Wonder if Mark #uckerberg is going to crack down on Left-Wing hate groups after this attack....
