When someone wants to prevent you from thinking, speaking or acting you make this gesture.
The person then understands that he is infringing on your Freedom and that he has no right to attack your Freedom.
It is done on the left side, on the left arm, the side of the heart because Freedom comes from Love.
It’s not aggressive at all.
We all want more Freedom and we want Freedom:
Freedom to think freely, Freedom to speak freely, the Freedom to act freely.
