Is that too small a sample to say "homosexuals generally mess with kids".
You don't recall that the underaged boys part of the story was Barney's then boyfriend was getting male children from a local school and pimping their services to grown men out of the basement of Barney's D.C. house?
There were two MOC's messing with pages during that earlier scandal, Gerry Studds (D-MA) with a male page and Dan Crane (R-IL) with a female page. Mr. Newt demanded their EXPULSION, but in the end, the House settled for censure. Crane lost his bid for re-election; the reason Studds survived the entire thing was that the boy claimed they were both consenting adults at the time, (he had been 17), Studds had the indignant, "My private life is no one's business" thing and survived re-election by his constituents until he retired.
"I don't think Barney Frank has been caught cavorting with under-aged boys (although it wouldn't surprise me)."
No, Frank just tried to help out a male prostitute who happened to live with him.
