Yes, that was a very sad case in which the founder of the organization was tossed out by a new crowd led by Kimberly Hahn so that they could try to force sex education upon Catholic home schoolers. Here's a working link:
Catholic Homeschoolers, A House Divided
This [sex education] "initiative," as it was dubbed by Mary Hasson of NACHE (National Association of Catholic Home Educators) owes much, if not all, of its endorsement by NACHE and company to the cooperation of Scott and Kimberly Hahn, as well as Michaelann Martin, wife of Curtis Martin, Catholics United for the Faith's (CUF) president. Moreover, Kimberly Hahn now sits on the NACHE Board with Mrs. Hasson and they are both co-authors of Catholic Education: Homeward Bound.Note in the Popcak article the way that Popcak uses his relationship with Scott and Kimberly Hahn as some sort of imprimatur for his bizarre ideas. Scott Hahn has been taken to task recently for publishing books that try to compare the family to the Holy Trinity, a comparison that just doesn't work, and that becomes blasphemous if you try to push it too far.
