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.
