(n.) A person who detests any kind of "-ist" (optimist, racist, sexist, feminist etc.). One who hates labeling of groups of people with similar views, interests, etc.
Richard believes that anything labeled under the "-ist" category is less than honorable and overall untrustworthy; he is an ists-ist.

In today’s America, if you happen to be white and conservative, and if you have the nerve to publicly state an opinion that is contrary to the liberal ~ opinion du jour, you will earn an “ist” title. Racist, sexist, white supremacist, misogynist, chauvinist, extremist, alarmist, egotist, obstructionist, segregationist and antlesbiangaybisexualtransgenderquerrintersexasexualist.
Richard has an opinion that offends me, therefore he is an ist.
