In Australia there are heaps of people like that. My Dad is probaly the worse, being Italian and all it's to him something different is the end of the world. My friends are really good coz I help them out all the time and in respect they leave me be. If anyone goes to bag me about it, I simply say I'm not a Monster.(coz i know wat happens2 animals) Or I simply spill y knowledge on them till they throw up.
One day though a kid (his sickin the head) said to me, it doesn't matter they are dead and his girlfriend (fake barbie doll) said who cares its not me. I simply smiled and askd her wat brand her make up is. And told her wat happens to the animals tested. She ran to the bathroom!! I turned to the boyfriend and told him a little bit about it but he said I was just making up shit and that if you dont eat meat you die. I told him I'm leaving proof of being alive and vegetrian. He then said so, animals dont feel pain and if they did they could talk to us. I let that slide as his a thick head.
The worse people are Europeans, I am one, Italian, they can't handle change or different and go on about it so much. I told my Aunty she is being stupid, I dont even feel like is a big deal and she is like I justwant to see you healthy. I find that you can show all alternatives of food to Italians but they just wont accept it. I.e; chucking meat in my food as soon as I look away. I've simply grown over them.
So at the end of the day I know how you feel but your always going to find those people.
