This work aims to analyse the intolerant speech against women on social media, specifically Facebook. With the internet, intolerance has spread, with women being a constant target of insults. Misoginia, estupro incitement, psychological harassment and other types of violence are becoming recurrent in the virtual environment and are widely spread through speeches disseminated by fakes profiles or by individuals who identify themselves. In that context, Facebook communities that self-call machists share hate speech or repudiation against women. Therefore, the choice of this topic is justified by the critical reflection needed on how women have been exposed to intolerant social media rhetoric. The social network chosen was Facebook, due to the countless mint communities advocating it. The methodology used for that work began with the search for the terms ‘male’ and ‘machista’ on that social network. As a result, some communities were chosen to analyse their intolerant speeches with the help of the bibliographic reference in books, magazines, scientific articles and websites. The theoretical benchmark is based on the ideas of the circle of Bakhtin, referring to the notions of dialogism, set out and signa ideologically. That analysis is intended to show how intolerance against women on the social network is built up.
