It is because it is effective.
Of all the frailties of human behavior, the easiest one to exploit is sexuality, most especially in men.
Men have disgraced themselves, thrown away their careers, ruined their marriages, emptied their bank accounts, and even betrayed their country, all for just a few minutes of sexual activity.
The fact that the walking human stains named Swalwell and Schiff persisted on the House Intelligence Committee until McCarthy (in one of the things he likely had his arm twisted behind his back to do, took him and Schiff OFF the committee) should be enough to see how deep the rot goes...Swalwell with Fang Fang and Schiff with his homosexual liasions that left young black men dead in motel rooms.
“Adam Schiff”
Was the name written with a broad-tipped black Magic Marker on the exposed edges of a many-pages-thick law book resting on the desk of the district attorney for New York, on the TV show, “Law and Order” - during one episode.
And don’t forget the “republican” pal of Schiff, Buck.
