I'd say toy guns are different. There's active intent and imaginative play.
A fidget toy is supposed to be something that we use unconsciously to help us focus on other stuff.
It's odd, to me, that one can squeeze a trigger as a fidget.
I'm someone who needs fidgets so I imagine the action and feedback is satisfying. But I'm uncomfortable with the idea of unconsciously squeezing a trigger.
I also live in a country where guns are not common which probably influences my perspective.
