I know exactly what they want. Meaning and money.
They spent decades fighting the good fight, and the cause was righteous. Problem is, eventually they ran out of victims. Now the people who made their living as professional activists when activists were needed (Al Sharpton, Gloria Steinem, etc) are facing economic doom if the battle is over, and the younger progressives grew up believing they would carry the torch, only to reach adulthood prepared for a war that already ended.
It benefits both groups to "find" victims, mentally and financially, so that's exactly what they do. But the only people you can inaccurately cast as victims are the mentally broken, and so we see the "homeless" drug addicts, those with gender dysmorphia, women who confabulate ridiculous fantasies of sexual abuse (e.g. the Kavanaugh accuser), men who are attracted to children, all become the oppressed.
It's not because any of these activists actually care about these "victims;" they want fame and money and found a way to get it.
