Exactly. It's something I said in several of my posts before: No toggle will be perfect, something someone dislikes will always slip through. Then they'll complain and the toggle will be useless.
I know, right? I mean, one need only glance at the ESRB Ratings Guide to understand that there are many different variables that might reasonably factor into rating any given videogame:
## Alcohol Reference - Reference to and/or images of alcoholic beverages
## Animated Blood - Discolored and/or unrealistic depictions of blood
## Blood - Depictions of blood
## Blood and Gore - Depictions of blood or the mutilation of body parts
## Cartoon Violence - Violent actions involving cartoon-like situations and characters. May include violence where a character is unharmed after the action has been inflicted
## Comic Mischief - Depictions or dialogue involving slapstick or suggestive humor
## Crude Humor - Depictions or dialogue involving vulgar antics, including “bathroom” humor
## Drug Reference - Reference to and/or images of illegal drugs
## Fantasy Violence - Violent actions of a fantasy nature, involving human or non-human characters in situations easily distinguishable from real life
## Intense Violence - Graphic and realistic-looking depictions of physical conflict. May involve extreme and/or realistic blood, gore, weapons and depictions of human injury and death
## Language - Mild to moderate use of profanity
## Lyrics - Mild references to profanity, sexuality, violence, alcohol or drug use in music
## Mature Humor - Depictions or dialogue involving "adult" humor, including sexual references
## Nudity - Graphic or prolonged depictions of nudity
## Partial Nudity - Brief and/or mild depictions of nudity
## Real Gambling - Player can gamble, including betting or wagering real cash or currency
## Sexual Content - Non-explicit depictions of sexual behavior, possibly including partial nudity
## Sexual Themes - References to sex or sexuality
## Sexual Violence - Depictions of rape or other violent sexual acts
## Simulated Gambling - Player can gamble without betting or wagering real cash or currency
## Strong Language - Explicit and/or frequent use of profanity
## Strong Lyrics - Explicit and/or frequent references to profanity, sex, violence, alcohol or drug use in music
## Strong Sexual Content - Explicit and/or frequent depictions of sexual behavior, possibly including nudity
## Suggestive Themes - Mild provocative references or materials
## Tobacco Reference - Reference to and/or images of tobacco products
## Use of Alcohol - The consumption of alcoholic beverages
## Use of Drugs - The consumption or use of illegal drugs
## Use of Tobacco - The consumption of tobacco products

And that list is by no means comprehensive! So no, 'toggles' are not the answer here - much better we tell those people who simply cannot tolerate a little M rated content in their popular entertainment to avoid the kind of entertainment that is likely to upset them so.
