Why must orthodox Catholic fight orthodox Catholic?

Jo Flemings, who I read somewhere is a convert from protestantism and the Catholic mother of a large family – including one Legion apostolic and a Legion brother (seminarian), I believe – responded in the comments section of Bonum’s blog. She asked why the alleged victims don’t come forward and alert authorities. I believe her question is sincere, given that two of her sons are with the Legion if I have understood correctly. She is obviously a mother concerned about her children. This discussion cannot be easy on her. Especially since Bonum is now part of a profession where human lives literally depend upon one’s honesty and integrity. Thus one can presume his trustworthiness.
