I was a late starter in the early years (November 1982) but as I recall it was called snowsurfing. I don't think I heard the words "alpine" or "carving" until the late '80s or early '90s.
It is a real pity that any division exists between the various styles of boarding and I think it's up to each individual rider to be friendly to everybody else on the mountain no matter how many planks they are on or how they choose to ride.
Mind you there are two kinds of boarders that annoy me: 1. People who run over my board in the liftlines, 2. People who sit down to strap up and block the exit ramp at the top of the lifts; and 3. People who are unfriendly. (Yes that's 3 types).
The only point of going boarding is to have fun !
