That is your belief. I respect it. My mom is a vegetarian and I respect her beliefs, she would cook meat for us as she respected ours.
To me, the world has been eating itself since the beginning of life. Wild animals die horrible slow deaths from sickness to starvation over the course of days/weeks to being eaten alive or left to die, and that is the natural way of things. If you want to live you have to die. You don’t have to agree with me, but you should accept that different people see things differently than you.
I don’t expect a person at the bottom of the economic scale to feed their family with expensive alternatives that they don’t understand, and you should’t shame them for doing the best they can with what they have or what they know. If someone has the means to eat along with their beliefs, then more power to them. But shaming others is not the way.
Lead by example. Offer affordable alternatives, give positive publicity, not negative publicity, to let people see how your way can be good. Allow people to see your way. Don’t force them or they’ll just dig in deeper on their own beliefs.
If you believe that then you should work to change people’s minds, like actually research how to do that. The way you currently approach it will only make people disagree with you out of spite. Good luck to you.
Some people really think being a good example of the product of their beliefs and being obnoxiously obtuse and argumentative about their beliefs are equally effective at persuading others to think like them.
I can tell you no person ever in humanity was convinced by the latter.
