Re: “I saw his ass yesterday”
And I haven't seen a setting in Twitter that lets me define what language I am posting in - I post in Germany a (British) English.
If AAE is not an official language and if the text isn't marked as AAE, how is it supposed to differentiate between plain English and AAE? The only thing you can do is try and recognise the base language and then flag any derogatory or racial words.
Given I don't live in America, the whole topic of AAE was new to me, upon reading this post.
