> One of the original people demanding “define a woman” was a law maker. If we’re making laws that use the word woman we need to have a stringent definition.
We don’t (and, contrary to a sibling comment, this is not particular to common law, it applies in civil law jurisdictions as well, though it may be more true in the common law). If every word in law needed a “stringent definition”, the law would be so full of definitions you’d never be able to find the rules that actually apply them to the real world. Laws sometimes need stringent definitions, and they sometimes need disambiguation between plausible alternatives that don’t actually require a stringent definition, and sometimes they get by just fine with no definition at all.
