Yes, starting to understand more about animal ethics, both from the point of view of fundamental animal ethics regardng animal liberation/rights, as well as specific knowledge about poor conditions and often terrible suffering animals face day to day, could, albeit depressing, help you to build a strong mental resistance to dairy and eggs that could help you with your diet.
For instance, it seems to be that eggs involve more suffering and cruelty even than some meats!
And think about what dairy really is. Cows have to have just given birth to give milk, right? So the industry makes them give birth over and over again, while separating them from their young and making them live in tight spaces and have no life. It's a matter or harsh economic/business logic that this is the way to do it, so it's common practice.
Would you read some books if I gave you some reccomendations, or do you prefer movies? Or would you rather just stick with discussion on the forum and some short articles for now?
