America has been killing the taliban-ISIS for years because:
-they're a bunch of nutbags who think religion gives them authority to tell others how to live
- are self-righteous baddies who treat women as second class citizens
- demand everyone respect their religion
- dislike anyone who doesn't look and act like them
- have no problem collecting children and keeping them locked up away from their families
- brag about how their firearms make them invincible
- destroy the environment so they can gain profit and power
- distrust science and get their morals from a book translated centuries ago
- threaten to destroy everyone that disagrees with them
Seriously, who wouldn't want to get rid of a group of people who acted that way?
