I think it's not just about the "first-order "risk of infection itself. It's also the fact that a disease is a graph phenomenon, and gatherings will connect parts of the graph that are normally separate. This means that infections will lead to more than average amounts of secondary, tertiary infections. But on the other hand this may not matter as much anymore since we are in a late stage of the epidemic, and the disease is everywhere already. Also I don't mean to dissuade anyone from attending with this.
