>I believe for example if it wasn’t for biases and unequal opportunities, then the higher ranks in science and politics would be dominated by women. Hence, aiming at a 50-50 representation gives men an unfair advantage.
This makes zero sense considering the reality that women are underrepresented. "Aiming at 50-50 representation" could at best lift the disadvantaged group closer to 50% representation. It could in no way cause an underrepresented group to dominate a field.
