Why does it matter if SSL is commonly understood to reference the South Side Locos? Clearly people have been affected negatively by them. If you aren't going to stand up for them, how do we believe you really stand for black people and others who have been enslaved?

Before modern times, slave was just a common word to define people who had been put under slavery. Back then, you would've scoffed at the idea of censoring away a perfectly acceptable word because "it's not commonly understood to be offensive". That's what I gather from your refusal to recognize SSL as an offensive term referencing the Arizona street gang.
