That's slippery. "Society?" It' kinda like "they." If society decides a particular symbol isn't appropriate, it doesn't change the meanin for anyone. The original meme is about people who find the BLM name to be discriminatory being called racist because it means something else to BLM, and contrasting this to the various symbology of the Confederate flag. Who gets to determine meaning? The one who chooses the symbol or the one who finds it offensive?
