Likes to discuss the Catholic imagery on tarot cards with gnostic friends, trying to convert them, we have been dutifully informed via the Trad blogosphere. Even attends a Halloween party at a gnostic lodge run by his cousin, who invites him there.
For the record, I wouldn't do either. And for the record, this peculiar habit of his isn't worth being dissected publicly on the internet.
Charles Coulombe in my experience of him online is no less of a good, traditional Catholic--in the way he conducts himself publicly--than the rest of the online trad armchair scholars and pundits.
I for one like him, despite this peculiarity.
