I've noticed something that makes me feel uncomfortable and mentioned it and I've been told I'm imagining it or in easily offended neither of which is true
Well I'm on here a lot. And I've not noticed it. Nor have most posters, many who are regulars, so what does that tell you? We are all wrong and you're right? Is that really what it tells you? We are wrong that mumsnet posters are not inherently racist and you're right that they are?
Or could it be you are overly sensitive. Focusing on specifics and assuming it's due to skin colour when it's nothing to do with skin colour?
Are you saying no black woman can ever be critisiced? If she is it's about the colour of her skin? It could not be anything else? Like her personality, her attitude or anything else? Like it can be with white women? With black women it can never be anything other than skin colour and racism?
An intelligent conversation is not just agreeing with you when you call 12 million people inherantly racist and misogynistic, the latter particularly appalling because of the 12 million people you're accusing, most of them are women themselves.
Do you have this problem in real life? Where any personal slight, any critisism, you cannot see it for what it is, you always assume it's skin colour that driving it? Do you think if someone doesn't like a white woman it's because of her skin colour too? Or can you relate that to the person and look past skin colour?
Sadly racism exists, as does misogyny. You do neither cause a benefit by accusing 12 million people of being racist and misogynistic when that is very very clearly not the case. You would do well to listen to what we are saying and look deep into yourself to understand why you have such a sensitivity about any negative comment made about a black woman that you cannot take the comment as read, you always, always assume it's secretly driven by racism.
