So, if Mel were a Mayan of that day, he would still be refusing to see what or who his real enemy was - which was the corrupt, evil priests of a pagan religion hellbent on grabbing power, bloodlusting to behead people and attacking innocent people to garner more victims. So, instead of fighting the real enemies, the gentle hunter gatherers sat around the campfire singing cumbayah and burning their spears in unison, so when the evil priests came after them they had no guns . . er . . spears and were so weak from eating a diet of mostly tapir testicles they couldn't escape the imams . . er . . pagan priests nor protect their women from the terrorists . .er . . . rapists and pillagers. Mel is the perfect liberal Democrat, even if he isn't yet aware of it.
