I think this is a loaded statement. While there are, in fact, statistically proven differences for all three of those facets, the greater thrust that the OP was making seems to be that we are forced to dehumanize ourselves and others in service of an effort toward forced equalization, and that it feels very Orwellian.
There's nothing loaded about it; it's exactly what they're doing - removing specific bits of data from the person's CV.
I disagree with the whole premise that supports the first post; reducing someone to a short list of standard data points like age is the dehumanising action. It's exactly what is done when we wish to treat people as statistics.
Leaving them off is accepting that people's humanity can't be reduced to them.
