For context - both have had 'issues' in school with doing non-gender conforming things such as my daughter plays football and wearing trousers, likes batman etc. Son is a bit effeminate, very sensitive, ND, has his own difficulties.
Both have been briefed on several occasions in the past about hearing bad language but not repeating it i.e. Adults showing off, a meal in the pub with inconsiderate people nearby, family parties with exuberant family members, etc. I genuinely believe they understand this.
Have the film on record after it being on the TV over Christmas. AIBU? Is the language used too offensive, therefore overriding the greater message of the film? I think they both might appreciate the sentiment of the film but willing to accept it might not be appropriate?
