HA! :) Cardinal Newman was a convert. He had a reason to say such things, as he was a Protestant until his mid 40's (I think). I'm sure that many of the heavyweights on all sides who have switched have done the same.
Still, it is typical convert to Catholicism who says that he converted because he studied the history of the Church and convinced himself that the Catholic Church is the Church Christ founded. A typical convert to Protestantism would instead point to his distrust in what he correctly perceives as a Medieval institution, out of touch with modernity. The contrast is even stronger between Orthodox Church and Protestnatism, as the Orthodox Church is self-defined as the historical Christian Church above all else.
