No, a casual game isn't defined by genre, it's defined by being relatively simplistic and take minimal skill on the part of the gamer. A casual gamer is someone who plays games that are easy to pick up and go and that don't require a commitment to learn or play. Like Skyrim. It's just pick up and mess around, nothing to really try to figure out, character building is whatever, the quests are generic and everything is spelled out.
Um, no. Skyrim requires a pretty hefty time investment to do almost anything. By your definition Mass Effect, Dragon Age, etc. are all casual games.
A casual gamer is one who doesn't get invested in games or play them much at all, and simple games like those made by Zynga are targeted at casual gamers. If you play Modern Warfare 8 hours a day, you're not a casual gamer. It doesn't jive with what it means.
Nothing to figure out? I hope that's a joke, I really do. Just because something isn't Baldur's Gate doesn't make it casual.

Most casual games have similar basic features:
Extremely simple gameplay, like a puzzle game that can be played entirely using a one-button mouse or cellphone keypad
Allowing gameplay in short bursts, during work breaks or, in the case of portable and cell phone games, on public transportation
The ability to quickly reach a final stage,[5] or continuous play with no need to save the game
Some variant on a "try before you buy" business model or an advertising-based model
The word "casual" indicates that the games are produced for the casual consumer, who comes across the game and can get into gameplay almost immediately. Every month, an estimated 200 million consumers play casual games online,[4] many of whom do not normally regard themselves as gamers, or fans of video games.
Managing an inventory, buying and selling, crafting, looting, exploring, perks, magic...really? Nothing to learn if someone who's never played games picked up Skyrim?
This is the worst argument ever.
