I do not hold that feminism has any 'theoretical' basis at all.

A 'Theory' is a coherent and inclusive explanation; it is a system of ideas that explain as General Principles, independant of the facts, but simultaneously accounting for all the relevant facts associated with it. It encompasses all the relevant facts.

From a Theory, one can derive hypotheses which are testable outcomes of the Theory. If the theory holds true as an comprehensive explanation, the hypothosis in question will hold up under rigorous, controlled testing. Most hypothoses are designed deliberately to falsify the theory. The failure to do so, strengthens the case for the theory. Success at falsifying results in changes to the theory. The theory has to account for all its derivables. If not, the theory must be rejected or changed.

Feminism ignores relevant facts. It cherry-picks. It 'creates' false 'factoids'. It incorporates lies and mendacities. It changes 'truth and facts' to fit the overarching General Principles.

Sherlock Holmes made a cogent comment to Dr Watson one day. "It is a Capital error, my dear Watson, to make the facts fit the theory. One needs to change the theory to fit the facts.

The latter process is what Feminism refuses to do.

What feminism does is hold to General Principles that were and always have been incorrect and then force facts, lies, mendacities and invention into the maw, ignoring contrary facts and evidence. They will deny , object to, rubbish and calumnise any truth of facts that do not or refuse to fit.
