The big problem with taking the knee is that you have to make it clear why you are doing it as it then get bundled in with the BLM movement which you may not want to associate yourself with.
Perhaps change the gesture to lowering your head? Unfortunately taking the knee in of itself is meaningless but it seems that it has become too toxic. It began with the NFL player and Trump saw it as a keen opportunity to foment division and it worked. The BLM movement co-opted the gesture in response to Trump continual disparaging of it.
What are your thoughts on the 'raised clenched fist' that often accompanies. It reminded me of reading 'Soul on Ice' by Eldridge Cleaver, an early leader of the Black Panthers.
Not much has changed since the sixties, angry people on both sides of the divide, maybe a few less corpses, and plenty of 'heroes' who will no doubt turn into 'villains'.
