Intersectionality doesn't have to do with (People of Colour), it has to do with the intersection of issues for someone who isn't just oppressed in one category.
The intersection of poverty, Blackness, womanhood, sexuality, education, and country of origin are all incredibly important issues.
If you're not heavily an activist or working directly with your community, alongside the academic side of racial understanding the in the US, your opinion means jack-shyt in this thread.
I've been involved in social justice work and activism pretty much all of my adult life, until recently.
now this is anecdotal, but around these parts "intersectionality" is more often than not wielded by white folks as a way to sidetrack any sort of conversations that poc bring up in regards to their experience, any legitimate issues or complaints, and it's often used as an in to engage in Oppression Olympics.
i'm all for letting people cook regardless of their orientation or creed, but let's be real, this whole "allies" idea is bullshyt. REAL "allies" don't walk around shouting from the rooftops how they're an ally. it's a means to get some kind of cool points around here.
if I sound jaded, it's because I am, I've seen far too many of these white feminist and LGBTQ groups talk a good game(and they ALWAYS bring up "intersectionality") and at the end of the day they're just as racist as the folks in the Bible Belt.
are there some poc(non-Black) that are cool and down for the cause? sure. but I think by and large as groups they'd like to further their privilege in a paradigm of white supremacy.
as a matter of fact, all the identity politics and the Mr. and Mrs. "Me Too" fukkery just got to be too much and that's basically why I dropped out of the whole activist/social justice scene. They love shytting on black people, especially black men.
it really is Black People vs everybody
and historically speaking a lot of other groups have gotten further and benefited to the centuries of struggling black people have had to go through. and some groups have gotten where they are at Black folks' expense.
the Irish and Italians weren't "white" when they got here, they became white in large part by engaging in acts of anti-black racism like lynching and they also benefited from the fact that they could blend in phenotypically easier.
