We're all familiar with secret societies on the Left who have worked tirelessly to undermine the West. The Freemasons, Illuminati, and the Fabians were all secret or semi-secret brotherhoods that advocated a distinctly leftist ideology and infiltrated the ranks of government, academia, and media at the highest levels. There are similar groups today in the form of the Skull & Bones, Bilderberg, and the Bohemian Grove.
We have been struggling to reclaim our cultures and homelands from such pernicious influences. However, generally we operate through grassroots organizations and in the open, directly in contrast to the progressive, big government, satanist pedophiles.
My question is, is it practical to establish a covert organization where members know each other personally, knowledge of membership is kept to a bare minimum, meetings are personal and secretive, and members infiltrate important organizations? Activities could include leaking files, spreading disinformation, and co-opting groups. I avoid the term "secret society" because such groups are explicitly forbidden by the Catholic Church, and if it were a Christian organization dedicated to rekindle Christianity it would be beholden to answer to the highest ecclesiastical authority if directly asked.
What would the practical ramifications be? Could using the Left's tactics of infiltration and subversion be effective? It would naturally require a large pool of financial and intellectual manpower and even in a small group keeping defection from occurring may be difficult.
"Opus Dei" may already be such an organization but I am unaware whether they do anything like actively infiltrate. If there are any other right-wing hidden groups I am unaware of them.
