Do you not know what a metaphysic is? A metaphysic is something that affects the world without actually existing. Information is metaphysics. Law is metaphysics. Gender is definitely metaphysics. Science is too.
Y’all downvoting me because you’re taking offense to a word you can’t bother looking up the definition of. Peak stupidity and tribalism right here. You make up your identity(which is also a metaphysic) based on imagery and social appeal and sling shit just like chimps.
