Mind war really is brutal. It is a mistake to compare keyboard warriors to professional military doing awful jobs of infiltration or clearance. The tasks are different, the contexts are different, the resources are different. As an "agent of light" your greatest power is not obeying the orders of the wicked; and then withstanding the disapproval and persecution that results. There is no quitting, no discharge, no fallback; ordinary civilian society with a digital militia is the last bastion, after which everything is overrun. PTSD from watching eugenic genocide is just as much trauma as any other kind, and doesn't deserve some special approval or denial. Anons are making choices to continue while in psychological agony in an analogous way to those made on special forces training courses, but there's no instructor to give you feedback or pass certificate to say you won't need to do it again. That's the spiritual aspect, and in some ways is more severe than in formal military.
And those who come from both sides (former military - now keyboard) have their own unique view that makes it imperative to BE here, yet find dealing with all they have seen or suspect to be their own trauma. I think the number of former military who "get it" in whatever way speaks to the fact that it is hard not to start questioning once you run up against something that doesn't compute. That sends you down the rabbit hole. That leads you into the spiritual and physical REAL war.
Then again, every one of us comes from some form of life "traumas" that have made us who we are. Martin - you have such a gift with words and use this gift well!
