There's no problem with this game. The reviewer got it all wrong.
Firstly, if a kid actually gets any of the innuendo or sexual entendres, then obviously they already know what it's referring to. And if they don't already know, reading something that's a double entendre isn't going to corrupt them at all, cause they won't get it.
Secondly, I've been playing this game since 2005, when I was 12+. I am now 17+, and I do not drink, fight, or steal people's wallets (or my own pants). Neither do I condone violence or drunkeness. In fact, this game already teaches children the bad effects of being drunk - you can't adventure productively anymore, and if you do, Drunken Stupor adventures don't result in anything good. I can safely say this game has not made me any more of a drug addict, lover of violence or a "Boozetafarian". (Eg: Goofballs give you goofball withdrawal for TEN times the length of the positive effect, and if taken too many times, starts reduces your stats. If that isn't a clear warning, then what is?)
Furthermore, Alcohol does not play a major role in the game's scenarios. You don't need to consume any to win a battle, to socialize, or to even play the game. It just gives you a few more adventures, and if you drink too much, you get a penalty.
Thirdly, almost all games today have some element of "violence" (as this reviewer has put it) than what you see on Kingdom of Loathing. For example, First Person Shooters (self explanatory) such as Left 4 Dead and L4D2, and CounterStrike. Strategy games such as Age of Empires, Age of Mythology, Rise of Nations, StarCraft, Civilization, Caesar. MMORPGs like CabalSEA, or even MAPLESTORY! All of them have some element of killing to level up. Movies also have violence - Spiderman, Batman, Harry Potter, Avatar, even The Ant Bully, Lord of the Rings, and Shrek have plenty of "violence". Books too! Nancy Drew, the Hardy Boys, even the Secret Seven and the Famous Five have all sorts of criminals in them and these heroes engaging in "violence" to defeat them at points. If you can't stand something on KoL's level, you might as well spend all your time living as a mountain hermit.
What this reviewer needs to do is to take a reality pill, and realize that whatever's in the game will stay in the game. If anything, this game exposes children to the outside world, and allows them to realize some of the good and bad points of things in this world (eg consuming too much beer, taking drugs) without having them take it in real life.
The reviewer gives me the impression that all he'she did was to stare at a couple of screenshots of the game, noted down the "Drunkeness" meter, looked at the Wrong side of the Tracks, saw a few battles, and took serious offense at the entendres, all without truly analyzing it properly and letting initial prejudices get in the way (Which, by the way, is a bad example to kiddies! We don't want children to learn to judge a book by its cover, do we?)
