I'll preach it till I die : there's NOTHING WRONG with being ignorant- that merely means that you don't know, that you haven't had the opportunity/occasion to experience/learn (whatever it is). I've been handling the mechanical side of things....sheesh, since I was 5? 6? And it's so second nature to me/common knowledge, that I'm often guilty of just assuming everyone knows the basics. That's not the case at all, lol.
