[voltooid]

I am wondering now if you read the linked article. There is logic in not wanting a giraffe in your field of vision at a movie hall. Actively discriminating against people because of arbitrary conditions of their birth is not that logical. Active discrimination in the life of "untouchables" means that they are viewed as dirty or lowly. I think it is a bit simplistic to think that it is ok to actively stick to demeaning and derogatory practices because it is societally accepted or because that's "just how things are".
