After seeing how powerfully this issue resonates with people, I wouldn't mock it. I've been partly persuaded, too -- I might not be doing my job as a DM by letting people charm all the time without affecting their alignment.
I remember stopping for red lights in Grand Theft Auto, the first time I played it. Good times.
Mock it? Yeah, maybe a little. I think because the assumption is made that people should play the same way and characters should have the same values as we have. Yes, it is morally wrong to take someones free will away from them, but its no different than killing a living creature (which is kind of what the game is about). And not everyone plays characters that share the same moral values that we or the player does.
I don't think I have ever been in a game where anyone actually mind-raped anyone, but in the Exalted game I run the players are very much playing "the greater good" kind of characters and many an npc has lost their free will to the Zenith and Eclipse. But I don't see anything wrong with wanting to play flawed characters who make bad choices (by our standards) as long as everyone at the table is cool with it and the GM makes sure the consequence of those actions are properly realized in-game.
