But this is a deeply stupid story with a lede that basically says "I'm unfamiliar with even the most most famous 90s hip-hop". Tan, like many, many, many Internet commenters before him, was quoting Tupac's Hit 'Em Up, which, unless you think Tupac was literally calling out hits on Chino XL, was not intended to be a true threat at the time, and certainly couldn't reasonably be taken as one today.
People come up with all sorts of cringey rationalizations for how this is anything more than someone on Twitter faceplanting a dad joke (sorry, but 2Pac is now dad music, I don't make the rules). That's because the rationalizations are more narratively interesting, which is a pretentious way of saying "fun", and fun beats reason every single time.
EFfective local politics? Definitely not. But then, if you oppose what Tan is about in SF, that's a good thing, not a bad thing.
This is an off-topic dupe story and by rights it shouldn't be on the front page, but, whatever.
