There is this one kid in my class I've been dealing with for awhile now. Most of the kids know I'm a pagan and he constantly mocks it by saying he's a wizard and just being down right ignorant, any advice? And I know he won't stop even if I tell the teacher so that's not an option.
I've experienced similar. Best to ignore it and let them live in ignorance. Go to the authorities (counseler/principal) if it gets too serious or physical. They will take care of the problem. Since you live in America, you have the right to religious freedom, but you are not safe from criticism. No religion is safe from criticism.
