But if you put it like that, I'm only doing the same thing as you are. I'm ascribing what you say to the perspective of all Catholics, the same way as you are ascribing what you heard from a few Protestants to every Protestant church (which is hardly monolithic anyway, as I'm sure you already know).

That's why I'm saying it's not a good idea to paint in such broad strokes. I honestly see no reason for Catholic animosity against non-Catholic Christians, and vice versa. I may not agree with the practices of the Catholic Church's hierarchy and the historical incidents of persecuting its own (yes, even before the modern era), but I am not so blind as to be unable to see the good it has done, and the fact that doctrine-wise there's barely any substantial conflict. At the end of the day, Catholics and 'Protestants' worship the same God, and I wish more people would see it that way.
