Don't apologise.  I have not read Potiphar's Wife but I am familiar with the opinions of its author. 
I am opposed to Catholics like Kieran Tapsell adding to the plight of his Church by publishing books maligning it in the public square. We have so many enemies outside our Church, we could well do without the Fifth Column.
The molestation of children by clergy on the scale it has occurred since Vatican II is over. In the future it will sadly still occur here and there such is the imperfection of human nature due to Original Sin.
