Well said! Thanks for the link to Bishop Williamson’s talk on the topic!
This subject hits home for me. I was enamored with and drawn to paganism, ethnonationalism, racism, occultism, and nαzιsm for a while after my disillusionment with religion in general and the “Abrahamic faiths” in particular. In combination with my reading of Nietzsche I almost decided to embrace that identity, but God gave me the Graces to make it to Traditional Catholicism and to rebuke the falsities in the above mentioned ideologies while embracing what is true in them as taught/tolerated by the Church.
You're more than welcome! Glad to see that you found the True Faith!
I have a similar background, though I was drawn to Fascism (as it was explained to me via some videos by a "third positionist"/nazbol type), and was in favor of Italian Fascism. I've come to understand that one can reconcile that ideology with the Church through watching the videos of a Traditional Catholic channel called "Rights and Duties" on this subject. In his videos about Fascism, he has pointed out repeatedly how Mussolini and other fascists had ideological views very much in alignment with the social teaching of the Church. If you haven't seen these videos, I recommend them.
Though, I would argue that "racism" is not really an ideology, or even a real thing, due to how vague its definition is. If racism = hating other races solely because of their race, then there sure is a lot of anti-European/anti-White racism in the world today.
