sh-t is perceived as all bad. Poo is perceived as not all bad.

It is certainly true that nothing is a "sin" (nothing is "all-bad") and that people should not be "judged" because nobody is "all-bad" and therefore nobody deserves damnation but it does not follow that everything is all-good. That is the opposite mistake. Everything is definitely not all-good and anarchy is definitely not freedom. People that believe that everything is all good seem to be hyper-sensitive to pain which they seem to experience differently from other people (as though pain were all bad). Perhaps for this very reason they are the most militant anti-theists (and ultimately anti-everyone).
Many (but not all) theists perceive God as all good. Drug addicts perceive their drugs as being all good. The cults of personality surrounding Hitler and Stalin depicted (and their devotees perceived) them as all good.
To worship something is to perceive that something as being "all good". Worship (and all or nothing thinking in general) is not limited to theists and belief in God does not necessarily entail worshiping God.
I do not believe that anything is all good or all bad. In reality even God would have a shadow.
You are free to choose to believe that 2+2=5 just as long as you know, and arent in denial, that it actually equals 4 (after all what could you possibly hope to gain by lying to yourself?)
What difference does it make whether God exists? A person approached the Buddha asking, “What will happen after I die? What was my form before my birth? What is the source of all we see? Answer these questions and I will become your disciple.” The Buddha replied in this manner:
A man is shot with a poison arrow. Wounded, he refuses any aid, demanding answers to his questions. “Who shot the arrow? What is the poison? Of what wood is the shaft? From which bird came the feathers for the flight?” Surely he will die with these questions still unanswered.
The basic teaching of Buddhism is that humans are sick and that the cause of that sickness is cravings. Cravings are not the same as desires. Desires are normal and healthy and do not cause suffering. You desire things because they are desirable. You crave things because they are forbidden
