Let's be clear: using caricatures of indigenous people as mascots is an offensive oversimplification of entire cultures, and reduces humans to racist tropes and stereotypes. This is what these mascots do, full stop. They do not belong in any time, and least not in 2017. As has been noted by opponents of the current mascot, less than 1% of the SDSU student population consists of people of indigenous descent (a whole other problem? probably) and Aztecs existed more than 1,000 miles away--there is no local, in-group case that can be made for maintaining the offensive mascot, and instead we have non-indigenous, non-Aztec people declaring the symbol to not be offensive and demanding it remain. Ridiculous.
