Nastik is Kafir in Hindi. Gita is based on the fight for right even if it is against your brother. That does not make it a book teaching voilence.Islam gives the same right to fight agaist Humanity. If you think that is not fair, there is not point making sense to people like you. Islam will not have been the most followed relligion in the world if it was against humanity. You will only see hatred if that is what you want, and you will only get love if that is what you are looking for. Dont comment on something that you have not studied from a neutral perspective.
