I think it's pretty obvious - he thinks that those groups are reinforcing the idea that they're trying to dispel. From his POV, if you don't want people treated as different, it makes no sense for you to do the same.

... which isn't to say that this measure (or, in the field of technology, an analogous one) is sufficient on its own, but that it is necessary.
To clarify what I meant in my earlier post: Yes, they are different, by definition - one group is the majority, the others are minorities. That doesn't mean that they're different in terms of intelligence, ability, or worth. Treating minorities "differently", otherwise known as "helping", is logical. It recognizes that the majority already gets "special treatment", because those in the majority are already looking after each others' interests.
