I tend to agree. Like the Jihadist terrorists, they hope to use the Internet to incite Lone Wolf nutjobs to do the dirty work or to groom patsies for it.
Yep there might be one or two nutjobs that decide to shoot up a drag show - but there are always one of two nutjobs who decide to shoot up a drag show.
I guess it's possible some right-wing militia might plan something - hopefully they've all been infiltrated and the intelligence agencies are listening.
