I'm not really interested in what your take on communism is but objectively both of those regimes are prime examples of Godless, secular and modern regimes, result? Massive loss of life, the institutionalisation of muderous practices and policies. The church is far from the villain of the piece that its often cast it but its an easy target for tired arguments.
I dont believe the state has or should have the power to compell compliance or conformity with secular norms and mores or traditions anymore than I believe the opposite that a Church should, vie the state, be able to compell non-believers or followers into adopting their norms or mores or traditions.
Just out of interest what isnt logical about tradition and what is unreasonable about traditionalism?
