While I disagree with most of what you wrote, a good portion of it is a matter of personal opinion - except for this.
This statement is demonstrably false and should be obviously false to anyone who stops and thinks about it for one second.
Numerous Catholic theologians have spent long years explaining in great detail the substantial arguments against Protestant criticisms of the Church.
To ignore this fact is to ignore much of the history of the Reformation itself.
My statements are from personal experience and research, but the history of the Church and the Protestant Reformation can get pretty complicated to follow when attempting to sort it out for yourself.
Can you recommend something for me to look at ?
