I've heard many reactionaries claim that BLM activists only care about black lives if they're killed by a white police officer because it fits their political agenda. These people will then go on to talk about how many more African Americans are killed by other African Americans and point to the apparent lack of outrage to make the case that BLM is only motivated by an ulterior political (often described as "Marxist") agenda. But ignoring that police brutality fosters distrust for the authorities allowing for criminal elements to thrive, BLM is only one movement (key phrase, movement, not organizations) campaigning for civil rights. And many BLM supporters have also supported measures that would curtail gang violence such as increasing funding towards welfare, mental health access and education in the black community, having stricter gun control laws to make it harder for criminals to obtain guns (whether they want to follow the laws or not) and de-privatize prisons whos' profit motives create a system that traps and keeps many black men in a life of crime. But whenever such measures are proposed, many of the same reactionaries who complain about how "BLM activists don't care about black on black crime" try to block them claiming that "it's telling other people how to spend their money" (even though everyone pays taxes and has a say in how they're spent) and "don't take away my guns" (oh boo-hoo, you won't be able to get more guns than you need to defend yourselves). And the reactionaries will make other BS arguments like claiming that the areas with most welfare and gun controls have the most poverty and gun violence not realizing that they reversed the cause and effect. So given that measures have been put fourth to curtail black on black violence, the claim that "BLM only cares about black lives when it suits their political agenda" is just a red herring meant to contrive hypocrisy.
Can people not realize that BLM is just one of many civil rights movements some of which have campaigned against gang violence.
If a humanitarian relief fund says that lives in the third world matter and focus most of their relief funds on feeding the hungry, does that mean that they only care about lives when they die of hunger?
