A cow, or a horse, or a dog, or a cat -- is there any difference? They are all sentient beings, they all have feelings, they all want to live and they all love their family!!!!!
We all agree that it is morally wrong to cause unnecessary suffering and death to animals -- and condemn people who for example enjoy and promote killing innocent dogs just because they got tired of them. However, we must also acknowledge that all animal products-eating is unnecessary and is done merely for "taste" and "enjoyment". So if we want to be moral we must also act upon what we acknowledge -that causing unnecessary suffering and death to animals is unnecessary.
The minimum requirement in order to accomplish this is to go vegan and inspire other people to become vegans.
The eating of a cow or drinking cow milk is directly causing the killing of cows, the splitting of families, parents losing their children and children losing the parents, immense suffering and death. All animal products are causing suffering to and killing animals.
