The Roman Reigns bit was dumb, he made it sound like Vince listens to fans. He doesn't. The only way people widely accepted Roman in the end was he beat cancer in real life, the poor fecker.
People hijacking shows with chants won't make a blind bit of difference.
What he does listen to is sponsors. Last year they named a match after a woman who pimped out her wrestling students in the 60's-70's. Fans complained, no response. Fans sent thousands of emails to Wrestlemania sponsor, Snickers. Snickers responded and the woman's name was dropped from the match in a matter of days.
It's one thing getting an old dead woman's name removed from a match, it's another taking on the hellspawn that is American healthcare.
