In Fr. Trincado's sermon (in which he reminds us that not only is the conciliar church overrun with modernist heretics, but also homosexuals), he obsereves a link between modernism and homosexuality.
The key, I believe, lies in the worldliness of modernism (i.e., the desire to conform to the world, rather than fight it, which slowly pushes reverence for God out, and brings reverence for creation in).
If one reads the second half of the 1st chapter of Romans, St. Paul teaches us that idolatry is the cause of homosexuality
, and worldliness is a form of idolatry.
It is perfectly expected, then, that the modernist church would also become a homosexual church.
In fact, it is unavoidable, because the scourge of homosexuality is a punishment from God for having chosen the creature over the creator.
Here is St. Paul:
" Because that, when they knew God, they have not glorified him as God, or given thanks; but became vain in their thoughts, and their foolish heart was darkened.  For professing themselves to be wise, they became fools.  And they changed the glory of the incorruptible God into the likeness of the image of a corruptible man, and of birds, and of four-footed beasts, and of creeping things. Wherefore God gave them up to the desires of their heart, unto uncleanness, to dishonour their own bodies among themselves.  Who changed the truth of God into a lie; and worshipped and served the creature rather than the Creator, who is blessed for ever. Amen.
 For this cause God delivered them up to shameful affections. For their women have changed the natural use into that use which is against nature.  And, in like manner, the men also, leaving the natural use of the women, have burned in their lusts one towards another, men with men working that which is filthy, and receiving in themselves the recompense which was due to their error.  And as they liked not to have God in their knowledge, God delivered them up to a reprobate sense, to do those things which are not convenient;  Being filled with all iniquity, malice, fornication, avarice, wickedness, full of envy, murder, contention, deceit, malignity, whisperers,  Detractors, hateful to God, contumelious, proud, haughty, inventors of evil things, disobedient to parents,  Foolish, dissolute, without affection, without fidelity, without mercy.  Who, having known the justice of God, did not understand that they who do such things, are worthy of death; and not only they that do them, but they also that consent to them that do them.
[Footnote to verse 26:  "God delivered them up": Not by being author of their sins, but by withdrawing his grace, and so permitting them, in punishment of their pride, to fall into those shameful sins.]
Fr. Trincado observes that this is the environment into which the SSPX desires to immerse itself, and that consequently, in such measure as it succeeds in doing so, it will suffer the same homosexual infestation as the conciliar church, and you can take that to the bank.
Scandals like those at Post Falls will become more and more common, the more the SSPX sinks into worldliness (idolatry) to reform itself for entry into the conciliar church.
How can it be otherwise?
God "Who is not mocked" will see to it
(i.e., by withdrawing His grace, as is mentioned in the footnote above).
Every sin carries within itself its own punishment: For gluttony, there is obesity; for fornication, there is venereal disease, broken relationships, and the inability to maintain fidelity; for pride, there is heresy or schism.
For idolatry (worldliness), there is sodomy.
It is not just the modernist
church into which the SSPX would submerge itself. It is also the sodomitic
church of depravity and licentiousness.
There are already too many signs of creeping worldliness invading SSPX millieu not to notice.
Have they themselves noticed?
I write these words not to excoriate them, but in the hopes of waking them, from a motive of charity, and saving them from that fate.
