We, the Cruel Humans

Can you imagine that a lady is being forcefully impregnated, then she is separated from her newly born child, and then somebody forcibly takes away her breast milk? And this is done for years, until the lady can no more produce milk. At this point, the useless lady is killed and her meat is fed to others. Wow, the lady was "used" 100% of the time she was alive and also after her death. Just replace the lady with a cow. How can we be so cruel to cows? Why do we need to drink milk which is nothing but breast milk for the calves, and was not meant for humans? Who were those smart people who made humans drink milk from the childhood, feeding into our brains the idea that milk is good and nutritious for us? Why as adults, we never educate ourselves about the truth? Why am I just blogging about this, and committing myself to becoming neither a vegetarian nor a vegan? I don't have answers.
