MMORPG = Multi-massive online role playing game.

It has no connotations of hardcore from the word itself. Games like EQ gave it a connotation of hardcore. It literally means a bunch of people play an RPG together.

As for casual, it means accessible and that you don't have to dedicate large amounts of time to the game to make progress. Sure in the long run you do. But you don't have to sit down for more than an hour to see progress happen.

I consider myself casual although I play video games for 4+ hours on days I can manage to even play games >.>

Stop being elitist. Stop thinking MMORPG = hardcore. Stop thinking casual = bad.
