Dear Marshall,
The soft insinuation that I am ignorant, is really just an ad-hominem argument. The gentle implication that I am part of an arrogant and ignorant group is also an ad-hominem. I encourage you to avoid such arguments since you are quite completely ignorant of my knowledge of the subject.

Let's see if we can drive this back to substance. Instead of telling me all the things that are wrong with my upbrining, tell me what's wrong with my assertion that application design should be decoupled from database design.
