Do you then support the analogous argument that non-combat flight simulators are nothing more than terrorist training tools?

There are two options for interacting with the world in a flight simulator:
- Ignore it
- Crash into it

That's it. The controller has an array of buttons dedicated to ignoring the world (ie. not crashing) which also used to interact with the world (ie. crash).

I would assert that any argument about "exploration", which falls under your broad category of "ignore it", would be equally applicable to flight sims and GTA.
