In English language Judaic media, Marion Le Pen is described as a "conservative" Catholic. Since the ritual epithet "antisemite" is not used (that I have seen), I infer that she is Novus Ordo.
Does anyone here know for sure?
She is Novus Ordo, although she goes on the Chatres pilgrimage.
Of course she isn't actually 'conservative'.....Being 'conservative' in 2015 was a moderate just 50 years ago. And all these terms are french revolution terms ( I know).
If there was actually a "conservative" Catholic Candidate in France they would be for/ against:
The very establishment of the "French Republic", and support a restoration to Monarchy.
Not just opposition to Sodomite "Marriage", but sodomy criminalization.
Not just defunding government agencies that do abortions, but criminalization.
Not just opposition to muslim mass migration, but sending them back to their own countries.
Unlike her grandfather (who was more 'conservative' but still a lacking Catholic) she does not speak out against the h0Ɩ0h0αx and worldwide Jєωry.
She dresses immodestly (even for a mainline sspx), and from interviews I've read, she might be slightly less modern and worldly than the rest of the world, but she is nowhere close to being an actual Traditional Catholic in culture or politics.
Hope this helps
