HAARLEM, Netherlands, October 20, 2011 (LifeSiteNews.com) – The head of an infamous pedophile lobby group in the Netherlands has been sentenced to 3 years in prison for possession of child pornography.

Radio Netherlands Worldwide reports that Ad van den Berg, 67, had been held in custody for six months while police investigated the materials on his computer. Thousands of films and 130,000 photographs of child pornography, among which were 13,000 in which Van den Berg himself featured, were reportedly discovered in a raid on his house in December. He claimed the images were “for scientific research”.

In 2006, Van den Berg registered the Party for Brotherly Love, Freedom and Diversity (NVD) to stand in parliamentary elections. The party billed itself as a champion of children’s rights and was dedicated to legitimizing pedophilia. Van den Berg said that among the group’s goals was lowering the age of consent for sexual activity from 16 to 12 and eventually eliminating it completely.

Van den Berg was convicted in 1987 of sexual abuse of an 11-year-old boy, which he claimed was a “consensual” relationship.

The Netherlands is known to be the most “advanced” nation in Europe in its shift towards sexual permissiveness. Prostitution and same-sex “marriage” are already legal.

The Association Martijn, the parent group for NVD, continues to attempt to push for public acceptance of pedophilia. Labour Party MP Khadija Arib told current affairs TV program EenVandaag last December that Association Martijn should also face investigation on the grounds that it incites child abuse. Association Martijn says it promotes the “acceptance of pedophilia and adult-child love relationships.” The Dutch Public Prosecutor’s office, however, has said that there is no evidence to support an investigation.
