Earlier quoted context omitted.
> "Insulting someone's code is like insulting someone's kid." You are way too attached to your code. . . . What these guys said was still extremely rude.
I didn't come up with that quote. I believe someone famish like Martin Fowler did a few years back. > You are way too attached to your code. For most people this is subconscious. If you're not, good for you.
Someone who's so attached to their code that they can't accept criticism (even harsh criticism) of it is pretty much guaranteed to be writing crappy code.
You'll notice that harthur didn't flip out as if her child was insulted. Instead she asked for constructive feedback, a sign of professional maturity.
