Plzzz someone tell me why all this ignorance?

ppl complain about the movie 'cannibal holocaust' for containing scenes where animals have been murdered and they even call ppl who watch that as 'sick ppl'...huh...that is the most stupid thing i've heard....why don't we say the same about ppl being murdered?? why animals being muredered is worse than ppl being murdered? huh...ppl should care about ppl more and not animals...so what if animals are getting killed?? to be honest...that doesn't effect me or make me feel sad....it's ok...i don't mind...we kill millions of chickens, lambs, cows, fish to eat them so...what is the difference in movies? and it's not as pathetic as murdering ppl....what do u ppl think?
