I acknowledge that social constructs are inherently "natural" as they develop over time and are shaped by their environment. Basically, they've followed the process of natural evolution.

However, it's also our understanding that evolution does not result in the "best case scenario", just something that vaguely fits the circumstances.

I think it's perfectly valid to "dismiss" social norms in the pursuit of something better because a lot of social norms just developed by happenstance rather than having real thought or wider considerations worked into them.
