Some people recognize that language has impact on others, despite the intentions of the speaker. Those people may chose to adapt their language to be more accommodating, or ignore it.

Its like requiring all new buildings be handicap accessible. No one is mandating that everyone use a wheelchair, but instead we're building new things in a way to (try to) minimize the impact on the handicap. By telling architects that stairs are hard to use, and ramps are easier, you're telling people how to build for everyone.

Similarly, by telling people what words may have negative meanings, you're empowering them to minimize their impact on others. This is a suggested language update, not a forced way of speaking, so its even weaker than the handicap accessible requirement. If you meet this list with open contempt but you don't show the same contempt for a handicap ramp... then maybe approach the list with a different perspective.
