This section looks like it has been taken out of context. The cited message makes no mention of Furrydelphia or con-goers, and only specifically mentions one person.
The message also doesn't really look like a threat at all to me. The use of "depicted" makes it seem more likely that Dionysius intends to commission art of said person being run over by his truck, rather than a genuine threat to hit him with his truck. --V. CA (talk) 14:04, 9 December 2017 (EST)
