Individuals should have rights/value irrespective of group identity.
However, individual rights don't exist without a group in general. If you are the only living human, the concept of rights is meaningless to you in general.
I live in the US, so my rights are (supposed to be) protected by the state, in case anyone wants to take them from me.
If my neighbor decides I don't have the right to live anymore and murders me, then I lost my right to live. I only have the rights that everyone around me agrees to let me keep.
> It's dismaying that there is a huge segment of academia that wants to revert to this more 'natural' state.
The opposite is true. Academia is where we get much of the evidence that socially-constructed groups (based on religion, gender, race, etc.) are not biological and should not be the basis for granting value and rights.
