I'm hoping this 'Stop Funding Hate' thing manages to get some traction. I'm generally against trying to rally against papers for expressing a different opinion but the DM is a different kettle of fish - it's genuinely written hateful, horrible stuff time and time again, deliberately targeting certain people with their vitriol for the sake of attracting readers.
People have been trying to put pressure on John Lewis in particular, since their advertising in the Mail kinda goes against their whole family friendly, likable stance they've had in recent years with the Christmas ads. Their reasoning for not doing so is that they won't choose on a political basis, but the DM goes beyond that into more ethical reasoning.
