Hate speech in modern use is attested by 1990. The term is found in a translation, published in 1898, of the Anglo-Saxon poem called "The Fall of the Angels," telling of Satan's revolt, where it renders Anglo-Saxon hetespraece:

    Dear was he to our Lord; but it could not be hidden
    That his angel began to be proud,
    Lifted himself against his Leader, sought hate-speech,
    Words of boasting against him, and would not serve God.
    ["Education," vol. xviii, No. 6, Feb. 1898]

Faith based term, people are using politically recently.
