I truly believe that homosexual people, male or female, cannot help themselves for feeling attraction to people of their own gender. But that doesn’t mean that they have the freedom to act on it. There are so many temptations that arise in our hearts in the course of our lives. But that doesn’t mean we act on them. This is what religious life is all about. Self-discipline, with the help of the strength that communion with God affords. Let these people be friends. There is nothing wrong with that. But when religion begins to endorse what God has condemned, that is the beginning of hell on earth.
Also, the Catholic Church, in the 1400’s through the 1800’s organized “The Inquisition” Estimates of the number killed by the Spanish Inquisition," which Sixtus IV authorised in a papal bull in 1478, have ranged from 30,000 to 300,000 . Some historians are convinced that millions died." So although the church is against abortion, it also authorizes and encourages wholesale slaughter of people of other religions. Similarly, Estimates for deaths during the First Crusade ( launched in response to a call by Pope Urban II in 1095)
vary, but it’s generally accepted that tens of thousands of people, both Christian and non-Christian, soldiers and civilians, died due to disease, starvation, and fighting.
The question raised is "What Catholic teaching or doctrine do you find most challenging…). My conviction is that people who have the humility to recognize God’s dominion, regardless of their specific cosmology, rituals, etc. should all be loved and respected, and that God accepts their worship. After all, Jesus appeared a mere 2000 years ago. Does this mean that prior to that time, for hundreds of thousands of years, no one could approach God with a feeling of veneration and love in their hearts?
