Someone who smokes cigarettes whose partner dies of lung cancer from a lifetime of smoking who then decides to quit smoking and become an anti-tobacco activist should not be written off just because they're "only doing it" because it directly affected them via someone they love. Someone who is extremely rich because their ancestors made a killing selling oil who decides to become an "activist" after their mansion almost burned down due to wildfires should be mocked. Anyone can throw soup at a painting. Only the super rich can influence politicians (in america at least).
