First off you said social sciences were illegitimate also you have a very feeble grasp of what makes a field legitimate, we obviously have not found an encompassing theory for all society, but so what? The same is true fo physics, maths and so many other fields. You seem like a disgruntled stemlord and I would invite you to engage in some self reflection (and I understand in the west this may only be for the privileged few but) you should also try engage with these subfields a bit before denouncing the entire field.
