No doubt there are some.. a small few… who fantasize about a hot civil war. But I’ve never met any of them. OTOH, I see photos and read articles almost daily where socialists are calling for “revolution”, eliminating those who do not endorse climate change while calling any opposition Nazis, bigots, racists, etc., etc., which is a necessary step in first dehumanizing those who you want to kill. Those sweet young things that visit your house do not require Delta Force training. All they require is to first be radicalized, armed and shown how to use it.
As for the police, making a generalize statement that lumps all police into the “SWAT team, let’s kill them all” category is simply in error. No doubt some departments, as happened in Boston after the bombing several years ago, will trample on the rights of citizens without hesitation, but I certainly hope thats the exception. Spending over three decades in public safety I got to know a lot of cops. I believe there would be serious push back within most LE agencies if they were tasked to bully and possibly kill civilians for political reasons. Should it involve federal agencies all bets are off.
Consider, too, that local LE lives in the same communities as would those you believe would be targeted. They attend the same churches. Their children attend the same schools. They shop at the same stores. Becoming a jack-booted thug on duty then returning to the same neighborhoods you practiced your thuggery on would likely translate into a short survival.
I tend to discount a hot civil war even though I think we are currently engaged in a political civil war now. Without a doubt there will be violence. Already has been. But I do not believe now that it will be wide-spread and nationwide. But none of us have a crystal ball.
