Yep, unless California somehow deports every ICE / border patrol employee from the state, you can't expect California to be any different from the rest of the US from a personal security perspective.
It's one thing to decide, "Hey, I'm still willing to buy almonds but not bourbon," to help support a small farmer in a blue state. It's something else entirely to be willing to be snatched off the street and sent to an overseas concentration camp in order to "help" the underpaid hotel, restaurant and entertainment workers (but in reality just handing more money to the billionaires).
