People cross the street when they see you strolling up the block with your dog. They've seen how you get into picking up after the dog, just stuffing it into your pockets, no glove, no baggie. Leaving public restrooms with mason jars, not even having the decency to wrap them in brown paper to hide what you are doing. That big, toothy, brown grin.
It is a free country. No one has the right to judge you. If you want to live-stream your every bowel movement and collect donations from fellow caca lovers, that's your business. The post master cannot stop you from sending out hats and shirts that say "POOP PLAY IS A CONSTITUTIONAL RIGHT" or "POOP IS NATURE'S REWARD."
