I don't think a separate section will work. It's makes no difference. have you been on the Philosophy and Religion boards? someone will post about help finding a church and immediately all the atheists will pop up to jeer about the 'fairy' in the sky. When you remind them this is the Phil & Reli section so pls don't derail, they will tell you MN is an open space for everyone and you can't tell them where to post..and on until the thread is derailed and the OP driven away. They do with impunity.
No one will care if you start a separate board, it will be a battle everyday for it not to be derailed. There's a multicultural families board which isn't controversial, people come once in a blue moon looking for advice on things specific to BAME, hair products, its a dead board, hardly anyone goes on it. Why? Black women or BAME people are outnumbered on MN! we need their participation to have dialogue, and its that dialogue that is used to shut the topic down. We cannot push away the pack when they descend. We need their input, otherwise, who are we appealing to?
I don't think racism will ever be eradicated, I think it may be controlled to a point but you can't change the sense of entitlement in people, years and years of privilege is hard to erase from are a person's psyche and like they say "equality sounds like oppression to the privileged". The indoctrination of prejudice that comes as naturally as breathing air. After all, this is what we are asking white mothers to help with?
There are many well educated, intelligent and knowledgable women on MN. How can so many not understand a simple slogan, "Black Lives Matter"? more complex matters are discussed on MN and several women come forward and explain. We have senior lawyers on the forum. Above all, there are strong parallels to be drawn from gender equality debates. I disagree they don't understand. They are opposing it because it sticks in their craw, they don't like it and it angers them, how dare you! so they pretend to have misunderstood and pervert to mean something senseless.
I don't know what the answer is, there are very unique and amazing white men and women, they are truly amazing in their empathy, humility and willing to lay down some of their privilege to stand side by side with black people to help. So I'll work with those ones when I find them.
MN to me is a place to discuss daily banter but keep your race anonymous. The majority are not interested in discussing our issues.
