I am thinking about introducing a terrorist group as my main antagonist. They are pretty much like ISIS (and in the story have their origins tied to ISIS and other groups) basically they plot attacks in Western Countries. A lot of what they do is based on real life events. I worry for obvious reasons this will not go over well with readers. My other concern is the portrayal a lot of members of this group are well when I created the group I drew inspiration from Marvel's Hydra and GI Joe's Cobra that being said I don't want to glorify the group in any shape or form. Is this too controversial?
