Yes, justice has been served
All we can do is speculate what might've happened had the victim been someone else, say a straight while male. Personally, like you I'd like to believe the same outcome would've been reached but in today's climate of "some victims are more equal than others" hate-crimes laws, one never knows. They just announced on the news that the couple plans to appeal their conviction. It's pathetic that they refuse to accept responsibility for their actions.
