How do you feel about protesting in school?

I think it is great that your friend is standing up for something she believes in. The students and the school will be able to decide for themselves whether or not they want to purchase food from KFC at the end of this. She is just bringing her knowledge and her opinion to their attention and I find absolutely nothing wrong with that. At the end of the day KFC may still be in your school,but at least she knows she fought for what she thinks is right and maybe got a few people thinking a bit more about what food they put in their bodies. Sure, switching KFC for someplace like McDonald's isn't really going to help animals, the environment, or anyones health, but maybe she will be able to bring it to the schools attention that there are healthier options out there instead of fried chicken and you may get food from a more veggie-friendly establishment.
