Internals of state structures being mandated some terminology is not really a violation of free speech.

In theory there are two approaches to discrimination - the neutral and the compensatory. The neutral one is that eventually discrimination will dissolve if the structure is built truly neutrally. The compensatory one is to detect kinds of discrimination and compensate for them specifically. I can imagine both the former and the latter feeling nicer in theory. The former - well, no special cases, just prevent the structure itself from reinforcing injustice. The latter - well, everything in life is a special case, you’ll never have a perfect structure, so it’s better to work with what you have.

It’s like different kinds of interference in radio, requiring different solutions. In fact they are not contradictory and both have their place in a working system (I haven’t heard of such).
