Manu's Shadow on Gita's Path

When I thought I am done with the study of interpolations in the Gita after my critique, Inane Interpolations in Bhagvad-Gita (An Invocation for their Revocation) I was tempted to turn my attention to the seldom read but much maligned Manu Smriti*. While I found that that testament is Incongruent and its motivated castigation is nothing but flogging a dead horse riding a blind donkey (an eponymous essay is due on this aspect), nevertheless, I could discern Manu's shadow on the Gita's path that is sought to be placed here for a public view.
