> I know superficially why you think that: PDF are Good Guys killing Bad Guys, and ISIS are Bad Guys killing Good Guys.
Like I said, I feel no obligation to explain myself to someone who frames their questions in such an obviously bad faith way. But it does make me want to ask you a question - if you view people killing other people as all the same, do you see no distinction between ISIS suicide bombers indiscriminately killing civilians, and Russian airstrikes killing ISIS militants? If you can see a difference, then maybe you can figure out on your own why I view some armed combatants differently from others.
