Racism in New Advent

There is a popular online encyclopedia that Catholics love to cite called 'New Advent.' Unfortunately, it is filled throughout with racist commentary, so I refuse to cite it or consider it a reputable source. Examples of racism in New Advent include:

"The negro has a religious nature. His docile, cheerful, and emotional disposition is much influenced by his immediate environment, whether those surroundings be good or evil. Catholic faith and discipline are known to have a wholesome effect on the race. Observing men and judges of courts have remarked on the law-abiding spirit existing in Catholic coloured communities. Some elements of the white man’s civilization do not always tend to elevate the morality of the negro. The negro is naturally gregarious, and the dissipations and conditions of city life in many instances corrupt the native simplicity of the younger generation to the sorrow of their more conservative elders. (For a view of religion in these later times among the blacks in the native African home of the race, see AFRICA.) Contrary to a prevalent opinion, the negro, when well grounded in the Catholic faith, is tenacious of it."

"The exaggerations of the highly strung African character showed themselves. A hundred years earlier Tertullian had taught that flight from persecution was not permissible. Some now went beyond this, and voluntarily gave themselves up to martyrdom as Christians. Their motives were, however, not always above suspicion... The whole account is characteristic of the fervid African temperament. We can well imagine how the prudent Mensurius and his lieutenant, the deacon Caecilian, were disliked by some of the more excitable among their flock."
