Take the Bohemian Grove for example, where estalishment cream from all over the world engage in ritualistic behavior in the forests of Northern California each summer. The very word "grove" goes back to Biblical times. In the book of Genesis, it talks about those who would meet in secret and worship in the grove. In the ancient Phonecian language, it stood for the male phallus. That is why the tree is so important. It's a representation of the phallus, the very reason you have a "family tree".
The 4 sides of the Washington Monument are aligned with the cardinal directions (i.e., east, west, north, and south). To the east is the Capitol, to the west is the Lincoln Memorial, to the south is the Jefferson Memorial and to the north is the White House.
At the ground level each side of the monument measures 55.5 feet long, which is equal to 666 inches. The height of the obelisk is 555.5 feet, which is equal to 6,666 inches.
The obelisks in ancient Egypt were a representation of the male phallus, the Penis of the God Osiris. Why do you think we have an obelisk in Washington DC, the Washington monument? It has occultic significance.
The obelisk in Washington DC (District of Columbia), the male phallus, connects with the female ovum in the White House's "oval office".
So all of this comes out of a Pagan belief system. Notice I said Pagan, not Satanic. If Washington DC's Masonic architecture and the very symbolism of freemasonry is representative of the male/female relationship, could not the horned-hand symbol have it's origins in that ideology as well?
In Italy and spanish-speaking countries, "horns" are a metaphor for suffering the infidelity of a partner, not limited to husbands in modern usage. However, the use of the term dates from the Roman empire, since legionaries returning from the war were given horns as a triumph or prize. So, the use of the term is a mockery of the husband, victorious in the battlefield, but defeated in his own bed. The gesture of the horned hand can be used to insult the cuckold; the Italian translation, cornuto literally means horned (This sometimes causes confusion in Italians who are learning English and encounter the word horny). The Spanish word for a consenting cuckold, cabrn, has such an offensive nuance that it is a taboo word rarely used with its original meaning, "he-goat". However, according to the tone and the relation to the addressed, it can be even laudatory.
The horned-hand symbol is a symbol of virility. It's interpreted by some to mean that you are healthy. So it would seem to me that the horned-hand symbol is not an outward symbol meaning "I love you" but more an inward symbol meaning "I'm healthy", "I'm virile" or "I'm victorius".
