And you might have noticed that "insult" is rather built-into theological debate because it seems every time a new belief springs from another one, both sides insult each other as matter of doctrine.
But most importantly, the spirit of anti-Christ is insulted by the words of God Himself.
Why do the heathen rage, and the people imagine a vain thing? The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, [saying], Let us break their bands asunder, and cast away their cords from us. He that sitteth in the heavens shall laugh: the Lord shall have them in derision. Then shall he speak unto them in his wrath, and vex them in his sore displeasure. - Psalms 2:1-5
The fool hath said in his heart, [There is] no God. They are corrupt, they have done abominable works, [there is] none that doeth good. - Psalms 14:1
Why not all? It's definitely necessary to pay attention when a powerful group is lobbying to pass laws to require you to live by their standards. This does not mean you can't have an intellectual and academic disagreement with their position.

Absolutely. That was one of the things that really started to bother me while I was still a Christian. At one board the Calvinism/Arminianism debate forum had to be shut down because each side claimed moral authority and then mercilessly bludgeoned the other with it.
Discussions about religion are fundamentally inclined towards "holier-than-thou" arguments, since they tend to involve morality. In an argument about a scientific topic, a person can be mistaken or even ignorant (a situation that can be rectified), but in an argument about religion a person is more likely to be called wrong or morally debased (not so easy to fix). I couldn't count the number of times I've seen the "God, thank you that I am not like other men" speech in one guise or another.
