Using Shu et al., 2007's"Investigating The Nuclear Obscuration in Two Typesof Seyfert 2 Galaxies'(Shu et al., 2007)"as a prototype, we demonstrated that highsignal-to-noise ratio and better spatially resolved data can account for some of the ob-servations that are inconsistent with the Unification models of Active Galactic Nuclei.New data for the relatively low luminous seyfert 2 sources ((seyfert 2 with luminos-ity < 1041erg/s), which wouldn't be incorporated in the conclusions of Shu et al.,2007, are sought for and analyzed, to examine whether doing so would lead to the in-clusion all of all of Shu et al.'s sample into their conclusions. We accomplished thattask successfully and then embarked on the slippery slope of questioning some high-ly cherished concepts upon which current understandings of Active Galactic Nucleiare anchored and in doing so provided personal perspectives on the way forward for acomprehensive understanding of AGN.
