Don't be, FSSL, only about 5% of the people I talk to about this issue will take the time to look at it seriously. And by that I mean not only seeking to establish a basis for Regeneration in the Old Testament, but also addressing the various points which show Regeneration is distinct to New Covenant Promise.
I would like to see examples where I "did not make my case" and where the "passages had no relevance to the discussion ," but aside from that, I think we have played this out as far as it will go for now.
