“Name 3 reasons you are not Catholic (yet).”
I’m sorely tempted to say “because of the example of Catholics in these forums who won’t condemn burning heretics at the stake.” (Said only half-jokingly

)
Have you ever heard of a Catholic here who thought burning heretics was a good idea? That we should start doing it again? I haven’t.
It’s a terrible thing, but it was a different world then. Heresy was considered treason, and the punishment for treason was to be burned at the stake. It’s not something we are proud of, but it seems that critics always bring this up and ignore the great contributions of Catholicism (charitable works, taking care of the sick and needy, universities, music, art, architecture, canon law, international law, monasteries, preservation of books by scribes, science.)
But these things are usually forgotten. Also forgotten is the fact that Protestants have a lot of skeletons in their closets too–look what happened to Catholic priests in England during Queen Elizabeth’s reign (hanging, drawing, and quartering.) Protestants fought and killed each other as well (Lutherans vs Anabaptists.) We do live in a fallen world. What Christian church has sinless members?
And unlike Protestants, we Catholics don’t have the option to split from our denomination and start our own churches to avoid scandal. We come from a Church that is 2000 years old, that survived in the real world amid real history. Even if there are sinful members, there is no option for us to leave if we really believe we are members of the Church Christ established.
If I wanted to be in a perfect, scandal-free church, I would start my own today. I would have no baggage of a messy past to deal with–no Inquisition, Crusades, or burning heretics at the stake.
Then I will have established a pure, untainted church; that is until I do something sinful. Then I must split from myself, establish a newer, purer church, and start all over again.
