SJW is a criticism of faux-liberals. The kind of people who are tripping over themselves to be more politically correct and more inclusive than everyone else, not in the interest of promoting liberal ideals, but in the interest of promoting themselves and improving their social status.
Of course, that’s not what liberalism is about. It’s a horrible problem the left has these days.
That’s why in the video I linked about “Leaving the Left”, Dave Rubin says that he feels like what used to define a liberal (standing up for free speech) has now morphed into “If you disagree with me, then you are a racist bigot who should be thrown out and not listened to. Now onto the violent protesting that achieves nothing”.
