Invective is harsh language, abusive, often used as a form of rhetoric against a group. The description of a statement as invective is invariably a negative comment, inferring the person making the statement is merely being abusive, not making any actual points. The style of speech and commentary, however, is common enough, particularly on the internet and in 'grassroots' politics, where factual content is often mainly selective. Dictatorships are often founded on principles expressed as invective.
Examples of Invective:
Goebbels' 'Hymn of Hate' against the Jews is the classic case of political invective against a group of people.|
Lenin used invective as a primary tool of his speech making.
