Abby I understand that you are trying to highlight that the life of one animal (cow, pig, sheep etc.) is just as valuable as another (dog, cat etc.) but I feel the way you are going about it is counterproductive. The bacon sandwich reponse is what you will always get when you try and tackle this issue in a confrontational manner.
Can I ask you how long you have been vegan?
Most vegetarians and vegans have moved from an omnivorous diet. Most of us have eaten meat at one point or another in our lives. Yes there are some people who have been vegetarian or vegan since birth but the majority were once meat eaters.
We all had our own, personal 'light bulb' moments but we can't expect others to respond in the same way based on our own experiences.
Calling people out for eating meat rarely gets a positive response. You can't change a lifetime of dietary habit/culture/whatever with insulting comments.
You can't/won't change the way people think about food animals by insulting and demeaning them. All that will do is make them more aggressively omnivorous - eg a PP making a point of eating blue steak in front of a preachy vegan/veggie. That's pretty childish to be honest, sort of a 'nerr nerr I'm going to eat more meat just to spite you' but it's also a very common response when they feel people are telling them what they should or shouldn't do.
You need to take a different approach in order to get a positive response.
The puppy picture will have been computer generated, just like the 'humans are made of meat' one with the sliced up fingers (very realistic and boak making).
