As to Pagan temple in Poland. It’s all fine and great, my only reservation is that many Polish Pagans are associated with nationalist right-wing groups or political parties. For example head priest of the group, that is building this temple, is in a right-wing party, that is constituted of so ultra right-wing groups, that they’re basically fascist and there are efforts to delegalise them. :( So not exactly something I’d like to be associated with as a Pagan.
