this shouldn't be encouraged, it's another 1st world problem
We don't or at least shouldn't need 'protecting' from stereotypes, bad role models or anything we might see on the TV, on a billboard or on a computer. We seem to be encouraging a world where people are increasingly fragile and can't think for themselves, we need to tiptoe over endless eggshells to avoid offending them.
Obese people are told to be 'body confident' rather than to lose weight, they cost the NHS £5billion every year, there are so many of these body confident people about no-one notices any more, yet if you see someone who is anorexic then it's rare, people look and stare, this is despite the thin/athletic models in the magazines, on the TV, in adverts etc, or the slim manakins in the shop windows. They then use 'real women' in the adverts to avoid offence meaning that to be one you have to be overweight, if you are slim/athletic then you're presumably part of the problem! If you're a man that's useless around the house or can't change a wheel on a car then you're a stereotype, if you know how to fix stuff and don't have a problem with DIY and keeping the house clean then you're just another man that's keeping women down. If you're a woman who likes being a housewife then you're oppressed! Any model used will always offend someone, it's what they're there for, it gives them validation. It's a competition to see who can be the most frequently offended and self-righteous.
People don't need protecting, children should be taught how to think, not what to think. You should be confident in your own self and mind, your problems are your problems, they're not everyone else's, you're just as special as everyone else, i.e you're not special. No-one is interested in what you identify with if that's all you've got to contribute to the world. Go out and do something, be the best you can. If you find that the way a product is advertised offensive, awesome, don't buy their product, don't complain about it and demand that it's banned. We're bending over backwards for this tiny but very vocal minority of people who contribute nothing but demand everything. It's long past time we just ignored them and got on with our lives as all of these harmful adverts or stereotypes don't bother us, we're don't even notice them as we're just getting on with it. If you object to how something is advertised then just don't buy it. Marketers create adverts they think will help sell a product, if it doesn't work they'll try a different approach.
