Dor was the founder and president of the
SOS tout-petits association. He often led protests in front of hospitals which carried out abortions. He participated in several dozen of these protests. According to Neil Datta, leader of the European Parliamentary Forum for Sexual & Reproductive Rights, Dor was the French representative of the first generation anti-abortion activists, who appeared in the 1980s and 90s after Western countries such as
France, the
United States, and
Germany legalized abortion. This movement did not achieve its ultimate goal, which was to overturn the legalization of abortion; but Dor said "even on my deathbed, I will continue" his fight against abortion. Dor took part in the
March for Life in Paris on 22 January 2017. He stayed at
Denfert-Rochereau at the end of the march, leading a prayer to the
Virgin Mary. He was joined by
Alain Escada and a priest in taking part in the prayer. He left
SOS tout-petits in January 2018. He was succeeded by Dr. Philippe Piloquet, an embryologist at the
University of Nantes. ==Legal issues==
