Title IX

 We have 16 categories of protection here.  5 of them have to do with race / ethnicity:

race / color / ethnicity /  national origin / ancestry 

4 have to do with sex / gender:

sex / sexual orientation / gender identity / gender expression 

The other 7:  

Age, disability, veteran status, marital status, parental status, genetic information, religion  

Nor making fun of this, but it doesn't seem very well thought out, since some categories overlap considerably.  The acronym  for the office of civil rights and title IX sounds vaguely sinister, like an anagram for orcs and ticks: OCRTIX.
