You have only pointed out some similarities. That's not the same thing as being identical.
MEM is right. Crosshairs are used on scopes (including many nonweapon mounted models) and lenses as a tool to center your vision. Whereas a target is an object that you're supposed to hit with a weapon or other violent actions. Therefore, the use of targets in campaign rhetoric is a more severe incitement of violence.
How's that for splitting hairs?
targets are what you shoot at. crosshairs are what you use to aim at your target.
