I wouldn't describe 'safety' as the state of things after the last time feds glassed a right-wing adjacent group. When the feds 'glassed' Waco, a little known guy named Timothy McVeigh was there. He used it as inspiration to bomb a federal building at which there were 700+ casualties of which over 150 were deaths.
The feds were very much aware "Bundys" was not just the ranching family but a whole bunch of people and greater militia network. If they had glassed Bundy himself it would have been a total shit-show.
I probably agree with your position in general. I would note that from my position it's more about the politics of the right and how that's more tolerable for folks in power.
Consider Michael Reinoehl.
