Good. You read one article.
There's many more. Please read ALL of them. Yes, ALL of them.
And, BTW, those are just SOME articles I've read. There's more. One article isn't what I posted. And one article doesn't tell the whole story.
Just as one page selected out of a chapter doesn't tell the whole story, either. There's much more to a book than one page from one chapter. To see a theme, you have to read many pages, and a great many chapters, not a selected few and then believe you understand anything.
