Antifa is actually the shortcut of the term “anti-fascists.” This group is composed of people who would like to stop racism. They are anti-racist and they are meant to check the activities that are being done by the neo-Nazis. What makes this unique is that it does not have any natural leader but there are some people who consider themselves to be honorary members of the group.
Take note that they have the tendency to become violent at times. They have the tendency to harass those whom they consider being racists. They also harass those whom they believe are doing things differently from what they think should be done.
