That's kinda the point, he faces no consequences. More of his islamophobic cousins and friends get emboldened.
Swastika isn't a hateful symbol either IMHO. Indigenous people of North America, European pagans and South Asians were drawing it long before nazis took it. They even called it a "cross" not Swastika.

Arresting people for drawing an ancient symbol while ignoring proud racists harassing a muslim family for existing. That's literally how you build fkd up shithole societies.
