Well first you can't flip a player. "Flip" means "legs" above shoulders. Second if u put someone into the air u're also responsible for his safe grounding. Yes there have been worse that go unpunished but that's the issue with inconsistency. On this count Rolland gave a red card in accordance with the rule book. You can't just say "he killed the game" In the Football World Cup last year, we saw Nigel De Jong got away with not getting sent off for his kung fu kick so that the game "didn't get killed".
