The Church has "officially"
The Catholic Church has been abusive of people in church history. Defenders of the church typically try to minimize this, or to justify it, or to explain it away. In good conscience, I cannot.
The Catholic Church of today has corrected all of these problems (but there may be particular priests, bishops, or other Catholics whose conduct does not match the teachings of the church).
I should mention that none of the following examples concern doctrines of faith and morals and therefore do not "officially" contradict the Catholic doctrine of infallibility.However, the Catholic Church's claim of infallibility,which depends on various trivialities and legal technicalities, is not very satisfying — I can't imagine Jesus teaching anything like this.

Discrimination against Jews, Muslims, and other non-Catholics.
Jews and Saracens [Muslims] are not to be allowed to have christian servants in their houses.
1179 A.D., Third Lateran Council
This sounds like anti-Semitism to me. This is especially troubling because it appears in an "ecumenical" [all-church] council.
Jews shall be compelled to make satisfaction to churches for tithes and offerings due to the churches, which the churches were accustomed to receive from Christians for houses and other possessions, before they passed by whatever title to the Jews.
1215 A.D., Fourth Lateran Council
This is advanced anti-Semitism. This is especially troubling because it appears in an "ecumenical" [all-church] council.
We command both diocesan bishops and secular powers to prohibit in every way Jews and other infidels from having Christians, male or female, in their households and service, or as nurses of their children; and Christians from joining with them in festivities, marriages, banquets or baths, or in much conversation, and from taking them as doctors or agents of marriages or officially appointed mediators of other contracts. They should not be given other public offices, or admitted to any academic degrees, or allowed to have on lease lands or other ecclesiastical rents. They are to be forbidden to buy ecclesiastical books, chalices, crosses and other ornaments of churches.
1431-45 A.D., Council of Basel

Placing religious and economic restrictions on Jews in the Papal States.
Papal bull issued by Pope Paul IV dated July 14, 1555, Cum nimis absurdum
Popes practiced anti-Semitism.
Some printers have the boldness to print and sell to the public, in different parts of the world, books . . . containing errors opposed to the faith as well as pernicious views contrary to the christian religion and to the reputation of prominent persons of rank. The readers are not edified. Indeed, they lapse into very great errors not only in the realm of faith but also in that of life and morals.
1512-17 A.D., Fifth Lateran Council
I am sympathetic to the idea that false and immoral writings should not be allowed. But as history has shown (see Galileo) even a well-meaning church can get it wrong.
You have purposed with the favor of divine clemency to bring under your sway the said mainlands and islands with their residents and inhabitants and to bring them to the Catholic faith.
Papal Bull, Alexander VI, 1493, Inter Caetera

Papal bull, Pope Nicholas V, 1455, Romanus Pontifex
Slavery decreed by the church.

Why should popes decide who is to have the right to a country?
15 [It is an error to say that] Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true.
Pope Pius IX, 1864, Syllabus of Errors
This papal bull denies people the freedom to choose their own religion, declares the church infallible, allows the church to use force in enforcing its will, insists that the popes had no role in the great schism, declares that the church should rule the state, and states that Catholicism should be the state religion.
