Anyone has the freedom to stay or leave the Church, but reason for leaving being actions or words of one man, even if it is the pope, is short sighted.
If you want to learn about the catholic faith, read the catechism of the catholic church, it is that simple.
Jews are viewed positively of course, they are Gods chosen people, but it is up to them if they want to know Jesus or not in end.
Responsibility of a christian is to share the gospel and faith, but after the council they went on the road of anyone can be saved despite his religion or atheism, which is not true to a so-called "traditional catholic".
Basically you have liberal side and traditional side in Church but despite that, faith does not change even though some do their best and try to reinterpret it in heretical ways. That is nothing new, it is present from the early years of the Church.
