Except when you have groups using its name making it political.
That is why the movement collapsed in the UK and led to fifa and co ditching the slogan.
In the UK the movement attached itself to defunding the police - tory policy for the last decade, anticapitalism, and most problematically jumping on the israel palestein conflict, alongside sharing antisemitic conspiracy.
It then attacked the labour party which had supported the movement and whos voters were likely the main supporters of BLM.
Described here :
The curse of a headless movemdnt is that it permits bellends to use it to push political shite instead of respecting the movement.
Personally id consider the slogan fine in voting stations yet it is sadly not in a vacuum and has been politicised.
Simple test if it has been indirectly tied to a political movement / party:.
Would you relate a BLM shirt with a MAGA hat?
