[Dwarf Fortress] Why do dwarves and goblins even hate eachother?

Think about it. They keep slaves. We enslave animal men and force them to fight in the arena.

They consort with demons. We dig into hell and then weaponize it by opening the tunnels against invading armies.

They are warlike and slaughter other races. We turn the slaughter of caravans into an industry.

Why do we hate them besides pure racism? We should be bros.

When the world was made, Armok determined that all races should be bound to their creed, marked by holy men in the symbol [ETHICS].  While some dwarves, in periods of questionable judgement, have strayed from these, they have all remained true to the core concepts.

Dwarves shall not butcher and eat intelligent beings.  Goblins think this is a personal matter.

Dwarves shall not torture.  Goblins think this is acceptable.

Dwarves shall not murder other dwarves, break oaths, keep slaves.  Goblins do not punish these.

Dwarves shall not commit treason.  On this, goblins agree.  With that as their only real common ground, is it any surprise dwarves and goblins hate each other?

Then realise what goblins do.  They send out raiders, looting and killing dwarves.  They send out kidnappers, stealing the future of the dwarven people from desperate mothers.  And they lay siege, attempting to destroy everything that has been built over many years.  When did you send out an army to aid the dwarven legion?  When did you ever war in a way that wasn't about defence?  You kill caravans, but you may be surprised to learn many dwarves don't (and do you really think your caravan killing has been morally correct?).  And you may think making prisoners fight is slavery, but when have you ever successfully controlled a truly intelligent prisoner to do anything more than fight?  You haven't.  They don't become slaves in the arena.  They die, or they become survivors.
