You will be shocked (not) to find out that Q is not actually a high ranking Washington military insider. He's a not-so-high ranking helicopter repairman, pig farmer, porn peddler who lives in Manila who started 8chan named Jim Watkins.
I'm looking forward to watching the documentary coming out on HBO, because the harder question is why do people join this. For example, I still don't really understand what our Peter Pan really believes verses what he parrots from others. QAnon just seems to be an ideological "Las Vegas" where supposedly well behaved conservative Americans can indulge their fantasies of religious extremism, racism, antisemitism, hatred, violence, anything and everything goes. It's all OK now wink wink. That's what these people love about it, that they can indulge their crazy thoughts.... until it doesn't stay in fantasy land and it turns into real life such as the Nashville Bomber or the Jan 6 episode. Then the ugliness gets exposed for all to see.
If Q could kill they probably will.
