Of course, very little airliner training happens outside a simulator, which can you can stall without damaging anything.
You should get an introductory flight lesson, then you could ask do have a stall demonstrated and see which flight simulator matches best. There are a lot of signs you don't get outside a full motion simulator, such as wing buffeting and "mushy" controls.
It's the stalls caused by uncoordinated flight during a steep bank or snap spins caused by exceeding critical angle of attack, regardless of speed, that will kill you. The first is easy to get into in a trainer like a C172. The second won't happen (safely) unless you're in something with a bit less lift and more power, like a Pitts.
Maybe they should apply mild taser shocks to pilots stalling in the simulator. I'm not being snarky. There should be some kind of physical consequence of making bad mistakes, otherwise it's too disconnected from reality.
A simulator "crash" is not nearly significant enough to their reptilian brain. Their neocortex may register it as a failure, but for the reptilian brain is just a big nothing.
Adding some physical jolt may drive the lesson deeper in their psyche, that a crash really is a bad thing.
