A report published by the Advertising Standards Authority in 2017 stated “harmful stereotypes can restrict the choices, aspirations and opportunities of children, young people and adults.

If you see something which you deem to be offensive or stereotypical, you can complain to ASA on their website. Don’t let harmful stereotypes go unchallenged!
