Who are "they"? The NFAC? Who says they're (or that they have at least a few ex-)military? Oh, the leader. That's not a terribly reliable claim, but let's assume that it is true.
How many ex-military are cops?
How many ex-military are these "nazis", or otherwise are "white supremacists"?
What about the actual National Guard?
If the NFAC are "YOUR Military too", then so is "the enemy". Ex-military exists on "all sides". So you tell me where the "good people" exist.
Speaking of Nazis, do you have a single shred of evidence that Kyle was one? Or even a white supremacist?
Because if you don't then you're just committing a textbook act of demonization again. Just call all your enemies "nazis" and then that makes it okay to commit violence against them, eh?
