I guess this depends on where we consider the line for "peaceful" to be. If the culture shifted enough where your views were in the minority, there's legislative action that can be taken criminalizing raising and harvesting of animals for food (in the US they just did this with dog and cats for example, with the latest farm bill).

Whether you agree or not, if your behavior is criminalized, the matter is settled (as a point of law at least).

To be fair, I don't know that violence against you (or others) would really convince you that these lives are valuable or not, just that you might value not being violently punished for acting on your beliefs.
