WisCon management has the right to make whatever decisions they think best for the convention. I do not and did not dispute their right to rescind the invitation.
Today has been overscheduled (like many other days) for months, thanks to multiple appointments, rehearsals, and the writing itself, so there's no time for more commentary by me. I'm leaving momentarily for the next round, in the city, and won't be home for hours.
For that reason, comments are disabled. Any further statement will have to wait until I have time for it.
