The result of feminists and SJW's threathening, shaming, doxxing, and intimidating people into silence to prevent anyone from questioning and examining the ideology of the movement, further spreading false information and ruining people's lives and reputations.
Person 1: "There was no evidence that she was raped. So there no need to continue with the case."
Feminist/SJW: "IF SHE WAS RAPED, THEN SHE WAS RAPED! YOU RAPE APOLOGIST! FIND THIS GUY'S NAME AND BOOST IT! I DON'T CARE IF THERE'S NO EVIDENCE! HE'S A RAPIST!
Person 2: How is doxxing and threathening this guy going to help? You can't intimidate someone that didn't do anything wrong.
Feminist/SJW: RAPE APOLOGIST! TUMBLR IS GOING TO HEAR THIS!
Person 1: *to person 2* The echo chamber effect is in full force. They won't listen to you. They only listen to people that only have the same views as them.
