I would like for them to actually supply a few sources to their claims. From what I gather it is all hearsay which makes it completely irrelevant.
What is sad is, I came across a fundie who claimed they were Catholic for 25 years, though they knew nothing of Catholic Teachings. This person accused the Catholic Church of teaching the worship of the Blessed Virgin Mary (Cultus Latriæ) & that the Pope is considered a saviour, etc., I asked for some sources to back up these claims and got nothing but more accusations added. So I took the time to collect up some Catholic Doctrine and posted it, explaining what Canon, the CCC, The Baltimore Catechism, &c., all taught in regards to this persons accusations. What came next surprised me a bit, they wrote to me telling me to stop posting such evil text, that everything that I posted in regards to what the Church has been teaching for about 1977 years, was evil. The only thing I could do was laugh at this persons stupidity.

@Aron the world being flat was believed by everyone centuries ago, before Copernicus & Galileo. Have you ever heard of Nicolaus Copernicus he wrote six books: De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres) and dedicated them to Pope Paul III. Thus there were accepted by the Catholic Church. Protestants were completely against it, as Martin Luther said:
"People gave ear to an upstart astrologer who strove to show that the earth revolves, not the heavens or the firmament, the sun and the moon.... This fool wishes to reverse the entire science of astronomy; but sacred Scripture tells us [Joshua 10:13] that Joshua commanded the sun to stand still, and not the earth."
(Quoted in Thomas Kuhn, The Copernican Revolution, Cambridge, Massachusetts, Harvard University Press, 1957, p. 191.)
On the Catholic side opposition only commenced seventy-three years later, when it was occasioned by Galileo. On 5 March, 1616, the work of Copernicus was forbidden by the Congregation of the Index "until corrected", and in 1620 these corrections were indicated. Nine sentences, by which the heliocentric system was represented as certain, had to be either omitted or changed. This done, the reading of the book was allowed.
And the history of Galileo, it seems, has not been taught correctly either:
Ironically, both Luther and Melanchthon had rejected Galileo's theory off-hand. Moreover, many in the academic world were hostile to Galileo and condemned his theories. On the contrary, it was the Roman Catholic Church, not the "enlightened reformers," that sponsored Galileo's lectures and supported his honest endeavors. Pope Urban VIII, Cardinal Bellarmine, and many other leaders of the Church publicly Galileo's scientific work, many of them owned telescopes made by him and conducted their own observations.
Galileo was not condemned. In only one trial, in 1633 (not the two that some erroneously allege, as in 1616 his friend Cardinal Bellarmine only advised him informally), he was given a moderate sentence (the recitation once a week for three years of the penitential psalms, which he had already been doing anyway and voluntarily continued to do afterwards, a practice that would take only fifteen minutes per week) for publishing as pure doctrine what he was told to publish as theory. The basis of his theory was in fact false since he based it on the tides of the sea, which depend not primarily on the sun, but on the moon.
Galileo spent not even one single day in prison, nor did he suffer any physical penalty. On the contrary, during his trial in Rome in 1633, he was housed in elegant apartments with a personal servant. Thereafter, he resided for a time in the palace (which his daughter described as "so delightful") of the Archbishop of Siena, a supporter. He was never prohibited from continuing his work and studies, and was never barred from receiving visitors. In other words, instead of holding Galileo prisoner as a confessed heretic, he was indulged as a guest of honor. Galileo died at the age of 78 in his own bed, with the plenary indulgence and blessing of the pope. (Vittorio Messori, Levandas Negras de la Iglesia)
Moreover, the pope of the time, Urban VIII, had brought to the Holy See an interest in scientific investigation not shared by his immediate predecessors. Galileo knew him personally -- had shown him his telescope, and had won him to his side one night, after a banquet at the Florentine court, in a debate about why ice floats. Urban had long admired Galileo so much that he had even written a poem for him, mentioning the sights revealed by "Galileo's glass."
Maria Celeste, Galileo's sister, delighted with her father at this turn of events: "The happiness I derived from the gift of the letters you sent me, Sire, written to you by that most distinguished Cardinal, now elevated to the exalted position of Supreme Pontiff, was ineffable, for his letters so clearly express the affection he has for you, and also shows how highly he values your abilities."
