Just a quick update, I have a short article recently published on the Gaol Naofa site, which ties into an earlier piece on Oisin, Cailte and Patrick, and explores the tumultuous relationship between we as modern polytheists and the reality of a heavily Christian past. There are also two short videos which explore some of the broader points of St. Patrick's day, stereotypes, problems and so forth. If you've some time, have a gander.
