I mean every single one of these at once, as hyperbole to show why there's no such thing as an absolutely equal footing for competition.

I know many sports are divided further, I've competed in some like wrestling, swimming, and hockey that were divided to different degrees, but there was never anything close to a real level playing field as gender and weight and age even combined weren't enough to outweigh massive advantages like family wealth, height and reach, professional training/facility qualities, or time in the sport.
