Because the law doesn’t work like a set of logical propositions where having redundancy is strictly zero harm. If the law says “no one should be discriminated against; and by the way specifically theogravity should not be discriminated against” that would raise some eyebrows about why this clarification is necessary, wouldn’t it? Also imagine ever simplifying the law to get rid of redundancies in the future. “caste discrimination is now allowed!” etc. - lots of ways bad actors can spin this. I’d be very very careful about what’s put down on paper in cases like this.
