Communism and Islam are not conspiracy theories. They are patent conspiracies: real, formidable, and most effective, political and ideological conspiracies avowedly dedicated to eliminating and further preventing the Christian ordering of society (the sweet yoke of Jesus Christ in the Catholic faith of all ages). They are anti-Christ worldwide conspiracies, whore daughters of that great and terrible whore of Babylon: International Jewry.
Jewry (every manner of heresy/blasphemy), Usury (every manner of avarice) and Faggotry (every manner of lust/unchastity) are the three pronged trident of the spear against Christ today, and throughout Christian history. Communism and Islam (and Protestantism to a lesser degree, though just as real) are false ideologies spawned and promoted to debilitate, destroy and prevent Catholicism, the true religion founded by Jesus Christ.
Cuba, erstwhile Catholic and prosperous Cuba, is one of the many living testaments to the success of that anti-Christ worldwide conspiracy. That conspiracy is alive and well in Western Europe and America, and on the world-wide-web! Politically, in Western society, it takes the form of anti-teleology, which is called Liberalism/Secular-Humanism which puts man and this world at the center of reality, supplanting Christ/the living God.
Jesus said to them: Fear not. Go, tell my brethren that they go into Galilee, there they shall see me. Who when they were departed, behold some of the guards came into the city, and told the chief priests all things that had been done. And they being assembled together with the ancients, taking counsel, gave a great sum of money to the soldiers, Saying: Say you, His disciples came by night, and stole him away when we were asleep. And if the governor shall hear this, we will persuade him, and secure you. So they taking the money, did as they were taught: and this word was spread abroad among the Jews even unto this day. And the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them. And seeing him they adored: but some doubted. And Jesus coming, spoke to them, saying: All power is given to me in heaven and in earth. Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost. Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world. (Matthew 28:10-20)
Furthermore, the contagion of anti-Christ conspiracy is present even in the Church. The Church will always have Her Judas', those who claim to be within Her, allying against her, from within, which is the greatest conspiracy of all, the conspiracy of the sychophant Jew pretending to follow Christ but betraying Him for personal gain.
Then went one of the twelve, who was called Judas Iscariot, to the chief priests, and said to them: What will you give me, and I will deliver him unto you? But they appointed him thirty pieces of silver. And from thenceforth he sought opportunity to betray him. (Matthew 26: 14-16)
Conspirators are real, just as real as conspiracies, even within the Church herself.
A final note. I will also say that the stubborn promotion of the chaotic Novus Ordo liturgy and suppression of the Traditional Latin Mass, coupled with the deliberate instability of Bishop Ordinaries of dioceses and Priest Pastors of parishes are evidence of conspiratorial infiltration in the Catholic Church; the disorientation of our Sacred Worship and the constant disrupting of our local communities by the regular random removal and shifting of our beloved leaders under Christ. Bishops and Pastors need to be stable, left in their places to do their God-given job, for the good of the Church, and for their own good!
