I havent claimed to be an expert I have asked for support to claim that America’s education system is terrible as was inferred. You linked me a high view course with many different topics and have not given any indication that you know about this topic.
You speak in generalities and tell me to find out the specifics for myself. If you asked me questions about my field in computer science I would be specific and try to be helpful for someone wanting to learn more about it.
Yes I am lacking knowledge on this topic. But I have a brain and when I see someone disparage a country’s education system based off of a single percentage statistic I’m allowed to shit on it. The onus in on the person who makes a claim.
