Latinos and people with mental illness (and fat people) are kinda still acceptable targets. Poor whites. Men in some contexts. Asians in some contexts. One of the biggest issues with the whole anti-discrimination movement now is that it is inherently reductionist - it has to be some grand intersectional operatic fight with clear goodies and baddies who are always winners or losers in some deep conspiratorial structure of society, they can't appreciate that discrimination isn't always so black and white and that often context can matter because for the "theory" to work it always has to be about some imagined power struggle.
What? That isn't the argument most anti-discrimination people make.
Most argue that subconscious bias and wealth inequality due to historical reasons are a significant part of discrimination. I've not met someone 'anti-discrimination' who believes there is a deep conspiracy of people working to instill discrimination across society.
In modern times in the western world, conspiratorial sort of discrimination seems to me to occur more in pockets or if the culture of an organisation goes bad and festers. But it's rarely overt or widespread.
More subtle and nuanced forms of discrimination are still everpresent of course, but everyone I discuss and work with in these issues knows this all too well.
Oh I've definitely encountered rhetoric that suggests middle class white-appearing males have intentionally and in bad faith created discriminatory structures because their power complex is what gets them off at night. I did go to a very liberal college though. I hope that stance is not becoming mainstream...
