Anyone have an argument for vegetarianism against this statement?

yes, we are human and we have a choice. i chose vegetarian. if animals were killed humanely i might not have been veg. but since animals are beaten, tortured, diseased, and living in filthy conditions before slaughter, i remain vegetarian. if a bear eats a person, the animal is usually tracked down and killed. so, they are animals, we are animals. why is it not okay for them to eat us if we eat them? and please..... no one cuss me out like they do on facebook. im a 14 year old girl and dont mean harm to anyone.
