Is that what I think it is in my fire ring?

I had pitched the tent, set up camp, and collected a significant amount of firewood before I took my first little scouting hike for the evening.  It was a brisk Autumn day and I had seen deer in this part of the property before and thought I would build a blind or hang a stand to hunt out of tomorrow. I felt a little rushed, this was only day 1 of a 5 day excursion I had planned and I would need to be back at camp in time to start the fire, cook dinner, and prepare for tomorrow. After finding the spot I liked ( I still hunt from the same tree to today) I leisurely strolled back to camp only to find Items missing (food, axe, etc.) and human scat in my fire ring. I can't prove it, but I believe it to be some anti-hunters who own adjacent property. They know where I camp since they had walked up on me during an earlier hunt and told me in no uncertain terms that I should leave and if anything happened to their precious horses that I would be to blame. I never left and this is the only time my camp was vandalized and it has been years now but I still feel uneasy.  If a woman could do that to my fire pit, what would she do to me?  I wondered if anyone else has had a similar incident and if there is any rational reason for pooping in a man's fire pit besides being a crazed lunatic ( I don't think it is ancient Cherokee custom). Just a thought before heading back into the wilderness where it seems that just like in the city, man's greatest danger comes from man. I wished I had thought to take a picture that day. Poop in the fire pit is a lot like Big Foot, you never have a camera when you need one.
