You are aware that there was a number of completely innocent people who were disappeared int US black sites, because of some name mismatch, something they said somewhere or because their neighbor didn't like them. Now you might be white and have an English name so chances of that happening to you might be slim.
However if you do not believe that this is an issue that we have to work against i suggest you get out and develop some principles. You seem to only have issues with these things if done by communist governments.
You framed the question. Don't push the goal posts around by pointing to past autocracies. It might be a very small risk, but it is infinitely bigger than the risk from my own govenment - where the risk is zero.
Sure. But the original question was: do you think that that should worry regular folks more than the evil and abuse perpetrated by their own government?
I'm not worried about most people, I'm worried about the people that the USA does go after, because the USA usually goes after good people who rightfully criticized what they're doing.
The USA does drone strikes all the time, not only against minor targets, but with egregious collateral damage. Listing examples isn't even worth the energy because this is common knowledge and a simple google search would reveal hundreds if not thousands of these killings.
It was US Military leaks via WikiLeaks that first got Julian Assange onto the USA's hit list, and if and when they get their hands on him, they will make him disappear into a gruesome privatized prison system where he will have no right to be heard, because he published things the government didn't want people to know about.
I don't care if I, personally, will fall victim to this. Trusting the USA is a stupid thing to do, and you have to accept that they are capable of doing a great deal of harm to anyone they want to, regardless of nationality.
