The distinguishing of good neutral to me is how much you care for others. Good people want the world to be a better place - tip more, vote in ways they think help society, assist others in community groups, etc... even if you dont have a lot of impact, wanting better for other people (and not doing things to make things worse for others) makes you good, to me.
Neutral I see as apathy. A lawful neutral person fits into their spot in society, but cares considerably more about themselves than others (good people prioritize themselves too, but put more effort into others). While a neutral person may tip, vote, etc do things to make society a better place, if it's from the realm of wanting life to be better for themselves and not really caring about others so much, then that trends neutral.
While I still believe you are diluting good a bit, a lot more people fit in the later group so at this point my argument would be that you don't have a proper view of the world. ---
