"Such people will also be barred from serving in certain high-status and influential positions, like government official, reporter, CEO, statistician, and similar."
For all practical purposes, I don't think this would be so different from what we already have in the West for people like CEOs, government officials, reporters etc. These people seem to be kicked out as soon as they do something politically incorrect. They don't seem to have much freedom. For example, the CEO of Mozilla who gave like 1000 dollars to some anti-gay cause like 10 years ago, or the CEO of BP who hired gay escorts or John Derbyshire who wrote something unflattering about blacks.
Ok, it's not the government doing it in the West, but the majority mob. But does it really matter whether it's some elitist government or the majority in a democracy doing it?
