As an oldschool pizzagate researcher the most likely reason we are hearing about them setting their own place on fire, and comparing the Covington event to "debunked" pizzagate, is because they fear imminent happenings.
Whether they have any basis to fear being exposed now, or they just decided that it would be a better approach to attacking Q, I can only speculate.
There are happenings though, my friends. True happenings.
