His point is that your calling him "a crass imbecile" added nothing to your post and is a gratuitous ad hominam attack. You said it to hurt him, unless you have some other explanation of why you felt a need to call him that.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
