If true, your brother is not a life long Bengals fan. He is no fan at all. No true fan would abandon their team.I am a life long Broncos fan, and they could go 0-16 for 10 years in a row, and I'd still be a fan. I would never in any circumstances become a Chief, Charger or Raider fan. I may on occasion root for one of those teams in a given week only if it helped the Broncos standing/playoff position, but I still would not be a fan of those teams.Basically the way I figure it, your brother is either spouting off steam because of his frustration and when push comes to shove he will be back as a Bengals fan or he is a flake. I don't see any other possibilities.
