My feelings exactly. I see no personal attack. I do see a criticism of code.

If someone looks at my code and says "That's a stupid way to do it", they are probably not commenting on my intelligence.

If someone looks at my code and says "You're stupid and your code is ugly", then I might take that as a personal criticism. (But I'd still take a second (or more likely, third or fourth) peek at my code to see that it is OK)
