So don't yell at cons if they decide to put on the event this year; there are so many factors unseen by most of us and out of their control that might have gone into that decision.
We should inform ourselves about the risk inherent in going and make the best decision we can.
Support the con in other ways if you can:
+ Attend panels and events virtually.
+ Donate to causes (or the convention!) to ensure their survival.
+ Recognize con staff as overworked and underappreciated PEOPLE who are VOLUNTEERING for the community.
+ Be kind. Always.
