It depends on how you're measuring value I suppose. Research for research's sake is rarely pointless, contributing to the sum of human knowledge is a worthy endeavour if you're okay with being in academia forever which many people are. Society's relationship with gender is a field worthy of study in my opinion, regardless of the political radicalism that apparently originates in that field.
I'd argue that the social sciences need more people involved in them, not less. For example, the way behavioural psychology has been weaponised during the pandemic by political actors (particularly the British government) has been very unethical in my opinion but as the social sciences are often seen by the general public as a bit woolly there's not been an awful lot of publicised expert criticism in the same way, say, a government denying genetics in favour of LaMarckism would put angry biologists directly into every newspaper.
