Is it appropriate to use the term “African American”?

Based on a website it’s suggested this is no longer appropriate. This is what the site (https://s. wsj. net/public/resources/documents/stanfordlanguage. pdf) says:

Black people who were born in the United States can interpret hyphenating their identity as "othering." As with many of the terms we're highlighting, some people do prefer to use/be addressed by this term, so it's best to ask a person which term they prefer to have used when addressing them. When used to refer to a person, the "b" should always be capitalized
