"The defendant is showing no remorse, so let's thrown the book at him"

How is my saying the same thing in different words “knee jerk”?
Anyone that looks different then society in general’s perception of normal is going to be at a disadvantage when in a courtroom. Would my pointing this out have been ok had the example the previous poster I quoted used a flamboyant cross dresser or a baggie pants skateboarder instead of a biker?
The point I was making remains the same, if you come before the court looking or acting contrary to what they want to see you are starting from a negative position.

People seem to be assuming that a defendant must either be remorseful or stone-faced. There are other emotions he or she can have - fear or disbelief for instance. Even sympathy for the victim.
Plus, doesn’t the defendant get to make a statement before sentencing?
When I was on a criminal jury (for a minor case) we didn’t get to do sentencing at all, the judge did it after we were dismissed.
