well i dont "drink blood" so i dont know where that came from.
if you believe that eating meat is murderous and "utterly disgusting" then i can see how you would be offended. in fact i would think the entire world would offend you just about, seeing as how 99+% of humanity eats meat.
do animals offend you when they eat meat? just wondering.
you are obviously going to have to learn to accept and love others even tho you believe they are acting in an "animalistic" manner. this is not easy. either your beliefs will evolve as you age, or you will learn to accept others for who and what they are, or you will continue to be disgusted by all of humanity your entire life.
living your entire life in a state of utter disgust with everone wont be fun. people really do have good and loving traits if you can look past their evil meat eating ways.
