Pirc Defense

I have been using the Pirc defense (kinda on accident) lately.  I wanted to learn something to go against e4 and was trying to use KID and well....yeah.  So anyway my question, am I just playing really passive or is this how the defense is supposed to work.  From the way my games go it is usually 50+ moves with both players having 80+% accuracy and it is decided based on a blunder or a few mistakes.  

@1
7...c5 attacking his center was more active than 7...Nc6.
You were doing well, but 9...Nd4? blunders a knight. Why not 9...Ne7.

I will answer the second first. Yeah that was just a straight blunder. My thinking was either a knight outpost or if taken there would be trade that would go balance. Didn’t occur to me the bishop would move. So just complete insanity for a moment, the thought of placing a knight into an outpost that can be captured by a pawn instantly, dumb. 

As for the first point. I like that suggestion. I remember at the time getting anxious because my queen side pieces weren’t getting active and I was worried about how the game would go if I didn’t change that. But the pawn move looks superior in every way. 
Thanks for your comments

Does anyone play the Pirc against d4? Is that even a thing?

Against 1. d4 it will probably just transpose into the king's indian. It's up to white  to get the position with e4 which is unlikely for a d4 player.

I find the pirc difficult and unnatural to play. I guess in most lines you are going to want to play c5 and try to create more space for yourself. The top computers don't like it and they often would rather just sacrifice a pawn for not much compensation just to free up their pieces.
