Sometimes, there are already resources explaining more clearly and thoroughly than we could. And although I’m unsure if this case qualifies, there are definitely topics that can’t be reduced to a few sentences. Thus, a reputable link is often worth more to both sides: it saves the explainer time and effort while informing the target far better.
If you don’t want to engage with the content, I believe there are better ways to go about it than being rude to people who were likely trying to help.
