I'm a latecomer to this thread, but stalling and spinning is a subject on which I have strong views.
Any aircraft used in a flying club for stall or spin training is specifically designed and certified as being benign in that respect. The standards vary slightly, but are generally in the order of max. 20° wing drop at the stall, and able to recover from a spin within one turn.
Not all aeroplanes are like that, I have experienced a 12 turn spin and watched (from telemetry) a 19 turn spin - both should have been 4-6 turns. I have experienced 60° wing drop IN AN AIRLINER at the point of stall, and know of one aircraft that can roll 180° at the stall if the flaps are down. The Bulldog is well known for pleasant spinning characteristics,until you put on a bit of in-spin aileron....
Yes learn stalling, and spinning. By all means state that "stalls in a C152 / PA28 are a non-event", but you train for the day that you are flying something non-benign when it bites. I know of a C150 which recently nearly killed somebody in the spin - almost certainly down to a leading edge dent - it could happen to any of you, it's already happened to me but good training (AND PRACTICE) got me out of it.
