Unfortunately, that seems to be a malleable argument. Which way your stating that (you don't want to disclose your reasons for not wanting to have kids) will influence audiences seems like it will depend heavily on their priors for how generally-valid-to-any-other-person this reason might be, and for how self-motivated both the not-wanting-to-have-kids and the not-wanting-to-discourage-others could be.

Then again, I might be missing some key pieces of context. No offense intended, but I try to make it a point not to follow your actions and gobble up your words personally, even to the point of mind-imaging a computer-generated mental voice when reading the sequences. I've already been burned pretty hard by blindly reaching for a role-model I was too fond of.
