Whistling is right on our different philosophies being a source of conflict on other articles we both edit But in this article it s not a question of whether merging or having seperate articles is a better editorial decision it s a question of what the sources say The statement on Singer s educational quiz certainly makes it sound like she defines fertility awareness as charting both mucus and temperature and mentions the Ovulation Method as a related but distinct method Whistling is right though that a different page on Singer s website makes it clear she is including the mucus only methods within her definition of fertility awareness So this is one source for that position and I support including it in the terminology section of this article I am not following how Singer s position should override the position of the World Health Organization Contraceptive Technology and Planned Parenthood These are all authoritative sources they agree with each other and I see no reason to exclude them from this article Talk C
