Vegan Bullshit Bingo #6:
Food is everbody's personal choice
How can something that others literally gave their lives for be a personal choice? Food nowadays is globally produced and distributed and affects - like most of our decisions - many more parties and beings, such as animals and our entire ecosystem. Your taste in music is a personal choice. The freedom to choose what we consume though, should not limit the freedom and well-being of others. Be it through animal exploitation, destruction of ecosystems, inhumane working conditions in the animal industry, zoonoses and pandemics, multidrug resistant pathogens, waste of resources and further consequences, that lead others to suffer.

but I can't stand the vegans that try to put others down for eating meat

Vegan Bullshit Bingo #52:
Vegans think they are better than everyone
While it feels good to know that you have questioned traditions and made your own informed decisions in line with values that reject violence rather than promote it, you should not get on a high horse, because almost all vegans were once not vegan and everyone can take this step. However, completely refusing to address the issue is a difficult stance to take. By the way: Just because a vegan once told you an uncomfortable truth, they were not being mean to you. And even if you didn't like a vegan once, that doesn't question the whole point of veganism or justify continuing to exploit animals.

Nature is kill or be killed and has been since the dawn of time. Everything eats everything else.

Vegan Bullshit Bingo #1:
Lions eat meat too
Yes, animals kill in the wild - to survive. We humans are, as opposed to predators, omnivores. We know how to grow crops, vegetables, etc. and cultivate fields. We have a choice, a conscience and have ethics. Are you identifying with the intelligence and life situation of that of a lion? Do you also commonly ask yourself "What would a lion do in my place right now"? Are lions that kill newborns of other lions, for example, really good role models?
