It is no secret that white privilege shows itself in many ways under the law. White people get more psychiatric help than colored, natives, and Asian people. It is also no secret that mentally disabled people were called "retards " and "morons" throughout their lives. Although in the 21st-century things seem to have gotten better, only those who experience can tell you it's not. The same goes for the LGBT, many still prejudice it but under silence. Perhaps discrimination is just under silence now.
After centuries of white supremacy, the governments across America, Australia, and Canada as well as New Zealand finally apologized for their discrimination towards the natives. However, had it gone away? Probably not. Natives of those countries still report hostility from the immigrants and whites even today. Even under the court, they're less likely to receive psychiatric help and more likely to be accused of crimes and punished both emit. In Australia, native youths under the same crime would be punished twice as harshly. In America, many natives could not even speak out for personal discomfort.
Many research shows that white people are more likely to speak out for personal discomfort. If the colored-skinned person speaks out for their discomfort, they would more often be seen as maniac or temperamental.
The same goes for Asians crying or having a mental breakdown. Asians are known to suppress their emotions and act monotone. If an Asian person begins throwing an emotional breakdown the way Caucasians do, we're often seen as "sentimental" or "neurotic". Maybe that's why other races seem to be doing much better mentally than the Caucasians - because we're not going to be seen the same anyways.
Back in the 1900s, it was no secret that mental disabilities were called "retards" or "morons". Nowadays, we don't have these terms on them because it is considered discrimination. However, are these biases naturally gone away? Probably not. Autistic people, those with ADHD, and mentally challenged people report experiencing the most isolated. Why? Maybe because those around them quietly segregate them without saying "morons!". Nowadays, people are less likely to publically declare it but that doesn't mean it's gone away. Only the disabled people will tell you the discrimination they face, the ones underneath the surface.
The LGBT had been protesting for many decades to get the minimum rights they now have, to share the slightest bit of privilege that heterosexual cisgenders get. However, had the homophobia gone away? Probably not. Many transgender, non-binary, and homosexual people can tell you the hatred they face daily. Unlike the 1900s, people nowadays are much more silent about their hostility. Instead of calling out slurs, they're more likely to just stay away and seclude the LGBT from events. They know that using slurs would get them into legal issues, so they would rather self-segregate.
So you see, that hostility never went away. Disabled people are still called "morons" and "retards" but done in a silent way. People other than the whites still experience discrimination but not on surface levels. Prejudice overall never went away like it appeared to be.
