Thanks for this. It made me wonder. Human beings ARE animals, primates, to be precise. But in common culture we think of ourselves as separate from our animal kinship. I think the racism bit is due to people NOT knowing about our mutual belonging, loving it, valuing it, respecting it.
Racism, to my mind is not a contest between whether we value a human life more than an animal life, it is about all of us learning to respect all life. BLM works hard to make black lives just as valuable, as seen, as white lives.
There is no benefit in thinking another life: tree, dog, whale, reef, is lesser than. This just perpetuates the damaging attitude that some are better than others. An anti-factual position. That is a human conceit, not one made by nature.
