YANBU.
Created an account to respond to this. I'm a mum of 2 healthy vegan children and also an animal rights activist.
Speciesism is what makes people love some species, such as cats and dogs, and see other species as merely objects to be used, such as cows and pigs.
A true 'animal lover' would not differentiate between a pig or cat for example, in their concern for it not being tortured and abused simply for a meal.
I would urge anyone who doesn't understand what I am saying or who can't engage with this subject to watch 'Land of Hope and Glory' on YouTube. This will show you standard UK farming practices. If you feel this is something you would not like to go through yourself as a human animal then please stop funding for non-human animals to be put through it.
Animals are here with us, not for us, all of them.
Unfortunately due to ignorance and social conditioning, many parents are unaware of the health risks of dairy and meat for humans. Also, as a parent, are you really ok with paying for a mother and baby calf to be separated and the baby shot in the head, for milk you don't need? Are you ok with cows being artificially inseminated (yes, this is rape).
It's good that these discussions are happening on mumsnet and people are becoming more aware of these issues. No one is free until all are free and at liberty.
