It sounds like ChadleyDudebro has had a change in perspective regarding race and racism. Initially, he may have been open-minded and willing to challenge his own beliefs with evidence. However, the information he found instead led him down a path of racism.
This could be due to various factors - perhaps the sources he was consulting were not reliable or balanced, or maybe he misinterpreted the data he found. It's also possible that he was influenced by other individuals who shared their views and convinced him over time.
In any case, it seems like ChadleyDudebro is acknowledging his current beliefs as being different from what they once were, which can be a difficult thing to do. It might be worth having a conversation with him about how opinions can change and evolve based on new information or experiences.
