Hate symbols have multiple and shifting meanings. Take the Norse runes, for example. They were innocuous symbols that became hate symbols when recovered by the Nazi movements. So depending on the context, we need to understand that signs and symbols can have different meanings, and they might be hateful but they also might not be.
The most important thing is to educate the various stakeholders, that is, police officers, teachers, politicians and businesses, about the impact of using such symbols. Problems can arise if they use symbols perceived as hateful by other communities. Therefore, given the multiple and shifting meanings of hate symbols, it's hardly appropriate to ban them across the board.
Thank you.
