Hillary and I met at loggerheads on this forum. He was an avowed atheist, I was still a theist of some sort at that point. He rubbed me the wrong way - I rubbed back. We took our dispute off the public forum and jabbed on the moderator section. We shook hands, no one admitted defeat as I recall, and parted on terms that allowed both of us some dignity.
Not long after, Hillary said his goodbyes, both publicly and privately as I recall. To my knowledge, he has not returned to this forum.
In the final analysis, his words influenced me in time to explore my own depths regarding matters of God/spirituality/faith/agnosticism/atheism. Though he did not convince me [conscience level] of his points of view - I believe that if we ever met now, we would be of common ground on many matters. Dispute often is the genesis of introspection. This forum has aided that in me - and Hillary was a component of that internal war we all fight trying to find our real selves.
Of course, as these things go, he would probably reappear as a theist, and we would just trade corners. LOL
