You jumped on the discrimination against mums OMG OMG OMG train when simply, you just don't like the music your local radio station plays.
I don't like cheesy boyband pop - does that mean that the big local stations around here are discriminating against me? Nope, it just means I don't fit their listener profile very well anymore (now if it was back in the days of Bros and Jason Donavan pre-Iceland adverts - you'd be talking) and I switch to stations where I DO fit the profile.
That's not discrimination - that's just having a target market that you don't fit. I can't stand Radio 2 personally (husband loves it and keeps retuning the radio in the car - he loathes Radio 1 wiht a passion) - I don't sit and scream discrimination because it's not playing my taste in music, I just listen to something else.
Can't quite see how it's discrimination against mums either. I wasn't aware you HAD to be a mum to have the radio on in the daytime (damn I'll go throw mine in the nearest river now - how wrong I have been), what about all those people who work in places that have the radio on all day in the background, what about drivers who have the radio on in vans and lorries?!
