I tend to agree with the other answer.
The only reason why people react negatively to others is when they try and make strong, sweeping decisions for others beyond themselves....PETA, FDA, Government, CEOs, banks, etc.
People would have no problem with vegetarians if they wouldn't run around creating drama and hassles for those of us that realize that animals are on this planet for us to use for our benefit. We should NOT make them suffer, and we shouldn't instill them with fear and so on,but they ARE for us to use.
Don't make decisions for me......make me aware of you want to, but stay outta my face and let me decide for myself....I'm a big boy and capable of deciding what I believe. If you don't want a burger....that's up to you (not YOU literally), but if I want one....then serve it up.
