Describing something as a social construct and then dismissing that as meaningless is fucking stupid.
Nearly everything that humans care about, everything that defines their lives, is a social construct.
Gender, money, art, happiness and the pursuit thereof, love, success — every damn last one a social construct.
Social constructs are the analogues of physical laws, but applied to the human phrenic space. These constructs can be bent a little and shaped from nascence to near adolescence, but once established in most people they are as strong as carbon steel.
Inspired by this post, which I was thinking about again today.
