The laughable Left

In India left is associated with something bad or inauspicious. When my cousin started writing using her left hand, my aunt tried her level best to change it as it was deemed as bad luck. That was my first encounter with "left is bad". That incident and the subsequent inference kind of got tattooed my mind.
Now when I read these reports, I understand why communist parties are called the Left. They are not only bad but are also laughable and dangerous.
