The term "pro fanes" refers to individuals who support and show enthusiasm for a particular person, team, or concept. Its antonym would be "anti fanes," which describes those who have a negative or opposing view towards the same person, team, or concept. An "anti fan" may actively criticize, boycott, or even demonstrate against something they disagree with. Another antonym for "pro fanes" could be "neutral," which indicates a lack of bias or involvement in a particular cause or belief. A neutral person may not have any strong feelings either way or may choose to remain impartial in controversial situations.
