Needs We don't have a clue who the target audience was other than some women, somewhere. Quite clearly many women do not identify with that just be looking at the post.
And I think you are quite missing the point - the product is divisive. It is divisive because it is sexist - I.e. Telling a woman how she should eat her crisps because other women (somewhere) have said that's how they want to eat their crisps. The product is supposed to be a divisive - it is a deliberate marketing ploy to increase product engagement. Therefore Dorito's have used a form of sexism (however mild you may consider it) for marketing purposes.
If it wasn't sexist, they would just realise 'the QUIET crisp', but it's being marketed as a 'lady's crisp'.
And just to be clear, I haven't actually said that I have a problem with 'women crisps' and I think the marketing is rather clever because it will work - but it doesn't detract from it being sexist.
