I'd love my children unconditionally, but that being said I could never sit by and approve of them abusing their children. And circ is abuse. So yes, there would be some ramifications to our relationship if they were mistreating their children in any way.
Really, the question is kind of moot to me at this point. My son is intact, and we are very honest with him as why we left him that way. I just can't grasp the thought that he would want to mutilate his own genitals, let alone the genitals of his child. We can't predict the future!
