You keep saying "ISIS" like it's some magic incantation that makes everything else OK. Try saying "any organisation the government disapproves of" instead, and see how that fits your mental model of what's acceptable. For example:
> you're fighting the wrong things here, if you think that taking citizenship away from any organisation that the government disapproves of is the biggest problem.
I think you'll agree that this would be a big f**ing problem.
