Why the gnome hate?

[Optimystik]

Given that the only source we have of Kurtulmak's massive injustice is... well, Kurtulmak, history has taught us (or at least me) to assume such accounts are just a tad bit biased and take them with a large grain of salt.

But even if we take Kurtulmak, Grummsh, Lloth, Zarus, Laduguer, Deep Duerra, Maglubiyet, Urdlen, The Dark One etc. all at their word... if we assume that every god that offers the Good domain was a complete bastard to them during their formative years, and that each one reluctantly assumed the mantle of divinity to shepherd their poor disadvantaged peoples to a brighter future of intolerance... In what way does that excuse the atmosphere of racism, infighting and consorting with fiends/chromatics that every single one of them has carefully cultivated within their churches over a period of centuries, and show no signs of wanting to stop?
