There have been a series of posts about this on the wiscon lj community, as well. The more reasoned ones are under lock; the ones that are about how Hurt and Silenced congoers feel by Moon's disinvite are all (at least thus far) open to the public. My personal fave?
This one, where magentamn declaims, We've got to stick by Moon, cuz she's a woman! And it's rude to rescind invitations! Also, Muslims are evil! "I feel threatened"!
Also, W1ll Sh3tt*rly is being an ass about this all over the internet, but what else is new. Apparently Moon is being mobbed and censored and silenced and bullied. Possibly also someone kicked her puppy, I dunno.
