Has it occurred to Raggytash that after producing reasoned, detailed and valid descriptions of his protagonist's distain for other posters that this has been spoiled by his last sentence.
You will never be able to to reason with him; that is beyond the power of mortals. Discussion - the acceptance of reasoned arguments and modifying a point of view - is beyond him. He is to Mudcat what Julius Caesar is to Shakespeare -

I could be well moved if I were as you.
If I could pray to move, prayers would move me.
But I am constant as the northern star,
Of whose true-fixed and resting quality
There is no fellow in the firmament.
The skies are painted with unnumbered sparks.
They are all fire and every one doth shine,
But there?s but one in all doth hold his place.
So in the world. 'Tis furnished well with men,
And men are flesh and blood, and apprehensive,
Yet in the number I do know but one
That unassailable holds on his rank,
Unshaked of motion. And that I am he
Let me a little show it even in this:
That I was constant Cimber should be banished,
And constant do remain to keep him so.
(Act 3, Scene 1)

To insult him is to descend to his low level.
To insult him is also to confirm his view that the whole world hates and misundertands him.
To insult him feeds into his persecution complex.
