Where I think racial identity politics can become uniquely corrosive is that racial lines don't fall neatly along cultural lines, so a racial division is not always reflective of a cultural division. This is especially true of people from settled families in the US (been here multiple generations).
Like I said, in a lot of cases identities are reflective of some cohesive thing. For example, all people of a given religion have certain traditions in their interest. All people of a given sex have certain medical needs they are likely to utilize at some point.
But there is nothing that can be said of all people from any given race. There isn't a single consistent factor among them. But to keep the divide strong, people on either side of it will simply invent things in order to justify its existence, and this is where it gets nasty.
You're all English anyway.
I mean English as a language and an identity.
