you say: "I did not answer yes or no, why would I, that was for the woman involved (who turned out to be beethoven's mum) to do".The question was: would you recommend that she have an abortion? You chose not to answer.
you also say: "It is like that isn't it. Change an answer, and a whole line of answers will flip"
No, it isn't like that. Just because one exception (like Beethoven's mother) challenges the advice that most doctors would give other women in her position, doesn't mean that the advice given to the majority is therefore invalid.
Isn't that what your "Go" analogy is implying?
If not, please help me to understand what you're getting at!
