Wearing boden clothes does NOT in and of itself make you a "Boden Mum". Moondog, you just don't have what it takes to join their odious ranks.
Being a sterotypical "Boden Mum" requires a whole new mindset, one that is spectacularly lower middle class but social climbing and narrow.
The "Boden Mum" is usually to be found on AIBU bitterly resenting the presence of a SN child in a mainstream classroom or complaining to the head about the SN child having a TA/special cushion/insert other necessary resource. "Boden Mums" are the ones on the governors that help sneakily divert school funds away from SN to the veggie patch, or that tut at you as you drag your kid kicking and screaming into class 5 mins late, etc, etc.
They travel in nasty, spiteful little packs, and think the bedroom tax is a great idea. Independent thought is totally anethema to them. They are however possessed of a wonderful sense of entitlement regarding the use of that disabled parking bay you so desperately need.
Having been stereotyped so much myself over the years, I've retaliated. The caring carrot and the "Boden Mum" are my top two human caricatures when describing personality types I loathe in short hand. I'm now just waiting for the Catherine Tate sitcom.
No other group requires re-educating quite so urgently, (other than the muppets at Westminster). Hopefully over time, the drip drip of advertising like this will permeate the public mind and reduce some of the prejudice our kids face.
