If someone is engaging in murder, rape or robbery, it would make sense to call attention to this fact, and then perhaps do something about it, wouldn't it? Parts of the US government are CURRENTLY misusing the word "terrorist" as a very broad label. This is very dangerous for the reasons discussed above. It's important to call attention to this problem if we have any hope of halting it.

Yes - you call attention to the specific person engaging in those acts. When you overlook that requirement of specificity, you end up accusing people based on their membership in a class, eg 'all gypsies are thieves, X is a gypsy, therefore X is a thief.'

So saying 'the US government is doing X, and I think it's acting illegally because Y' - fine. But 'the US government is doing X and this will end badly because governments always oppress citizens' (an argument that has appeared here a lot lately) isn't fine, because it rests on a false premise.
