Read it again:
“In spite of my childhood indoctrination, as a young man newly committed to my Christian faith, I had a crisis of conscience in the late 1970s. Massachusetts Democrat Barney Frank was pushing the homosexual agenda. How could I, as a Christian, be committed to a party led by Mr. Frank? In the end, I could not.”
He was saying that Frank was pushing the homosexual agenda, which I assume was the case even before Frank came out of the closet (as I would expect nothing less from a liberal from Newton).
Maybe, but I'm skeptical. Frank wasn't elected to Congress until 1980 -- not the late 1970s. So the author must have been an especially astute follower of state politics on Beacon Hill to even know who Frank was. Hey anything's possible, but if you were to leave the Democrat Party in the 1970s, would you really leave because of an obscure state legislator -- at a time when you could have stood against Dukakis, Ted Kennedy or Tip O'Neill? All of whom were equally liberal, and vastly more important and better known? The story makes no sense.
