You will never convert large numbers of people to being vegan.
I do agree that brutal cruelty is entirely inbuilt into the industrial scale slaughter of animals raised for meat.
Personally, I care more about buying less meat from sources that I know rear their animals well, that don't travel miles in trucks to the abbatoir, to stand on holding pens in fear with the smell of death all around, but are handled by small local abbatoirs, where the death is as swift as can be.
I have even visited the places I talk about and because there is a direct connection between the abbatoir staff and the person who raised the animal there is a care there which the desensitised people who work on the massive production lines of death don't have.
I realise it is still death, but I don't have a problem with that, everything eats something to survive. I do have a problem with protected awareness of what is happening and drawn out terror, or slow and painful when you can do swift and over.
I'm lucky to live somewhere where I can access food in line with my ethical preferences.
I would like to see more societal push for a better death as I think that is more possible than coverting people to veganism (on a bigger picture societal level that is).
