If that is the case then have your son go into a retail outlet without you and purchase an M rated game. 99.9% of the retail outlets will not sell it to him without your direct verbal consent. For an industry standard that is
not a law it is being treated as a law by the vast majority of participants.

[/quote]At retail level we are not even allowed to sell with parental consent. The parent must make the purchase. At my store Even with a parent there if the child tried to purchase first I will refuse the sale of the game.

parental consent?

Why you're being asked for parental consent

If the date of birth on your Microsoft account shows that you're under a certain age, Xbox is required to request parental consent for you to use Xbox Live.

If you're an adult, but you got a message asking for parental consent, it's because you're a child in your Microsoft family.

Solution

If you're of an age that requires parental consent, follow the steps on your Xbox to have your parent sign in and add you to their Microsoft family.

If you're over the age requiring parental consent, have your parent remove you from the family. They'll have to sign in to
account.microsoft.com/family, select your profile, and select
Remove.

If you're unable to clear the message, contact Xbox Support.

Actually, (in the UK at least) the age rating is simply to purchase a game, and there's nothing what-so-ever against me playing it with parental consent...

Could You be a little more specific ?

Is it asking for Parental Consent?

When he tries to log in, does it say 'must have parent consent?'
