I've read that the particular line of "Yeah we don't do much reading" has been totally taken out of context in relation to the story.
Apparently they were referring to ancient cybertronian scriptures which the Twins had no idea how to decipher. Now that doesn't sound "racist" at all it just sounds like not to many modern cybertronians know their planets ancient writing.
Yeah. If i look at ancient egiptian hyeroglyphs, i can't read them. Hell, i look at cyrilic or kanji, wich are still in use today and i don't now most of them. What they can't read are those ancient symbols. Context, people.
