It's a form of communism/marxism but it's hard to explain in short (by design). It's basically an ideology that has substituted class struggle with race and identity struggle. There are oppressors and there are oppressed, and the oppressed need a voice and people to fight on their behalf. The oppressed also get elevated and receive special treatment (hence the capital proper noun), and at the same time this is all done in a subversive way in order to smuggle it or shoehorn it into the culture. Additionally, if you question it or point it out you are accused of siding with the oppressors and called names like bigot, racist, etc.
