> Rights and wrongs are inherently social constructs.

This is an assumption, and not on supported by debates in ethics. Once you start questioning everything, you'll see that some moral propositions appear to be unassailable, in that, no argument can simultaneously question the truth of the proposition without also descending into logical incoherency. The categorical imperative would be one such approach, although not the only one.

There are good reasons why most philosophers are moral realists.
