Why it Matters?
Comparator identification is the recurring defense point, since the plaintiff must identify persons similarly situated in all material respects and courts apply that requirement strictly, which defeats most claims where the alleged comparators differed in any relevant particular. Engquist's public employment bar eliminates the theory entirely in that context, which is a threshold defense worth confirming before analyzing comparators.
