Theer's a big game coming soon in Quebec, could be really interesting for you to see. Just contact R3con1, the member organizing it here. You'll see the skirmish aspect on a large scale, and that will give you an idea of the average NON-milsim game.
Alos, as said before, you want to be neutral, so you'll have to ask questions to players, retailers (both airsoft shops and big shops, like canadian tire's clearsoft section), autorities, parents, etc etc.
