Amen Brother- if we are going to Evangelize, whether as Protestants (yours truly- although I am heading towards the RCC) or as Catholics my view is we have to be brutally honest and truthful about the past. This is actually in line, with what I believe is the official RCC position, that the Church Triumphant is infallible but is defectable because it is headed by humans- with all their inherent frailities . Both RCC and various Protestant denominations (as pointed out here and elsewhere) have stains on their past because of bad decisions and the thinking thaleads to things like the means justifies the end (along the lines, in some cases of case of “I will kill your mortal body to save your soul”).
As Christ said :

and the truth shall make you free
