Covert discrimination is often hard to spot because it happens as personal microdiscrimination against one person or few people only without them belonging to a common minority group. As such, the people discriminated against are not protected by any minority group anti-discrimination measures, and are often abused without the abuse being detectable by outsiders because the abusing discriminators treat outsiders without discrimination, so they become none the wiser about the microdiscrimination happening against the one individual or few that are discriminated against. That is why I wrote a guide to spot covert discrimination in the Ruby Community and beyond. https://andymaleh.blogspot.com/2024/12/how-to-spot-covert-discrimination-in.html
