The motto of the AIW is conservata veritate, which translates to "with the preserved truth".
This motto reflects the inclusionist desire to change Wikipedia only when no knowledge would be lost as a result.
I am a strong inclusionist. I see absolutely no reason to remove correct data from an electronic database for correct information.
I'll modify this statement to say I am in favor of removing articles that are self-aggrandizing (creating your own article is tacky), can't meet even a modicum of notability (sorry, Billy, the fact everyone knows it was you that threw the spitball at lunch doesn't count), or has no relevance to more than a handful of people (the fact you have been elected president of your own fanclub falls under this heading). But by and large, I tend to disagree with most deletion nominations that fall outside these lines.
