If your code review makes the coder feel personally attacked or embarrassed, you're not doing something right. Code reviews are meant for 2 (or more) way communications and discussions in order to hold quality of the code up to a standard, not a opportunity for the reviewer to feel superior and attack others. Commenting things like "this line is poorly written" is not helpful to anyone, instead try "do you x would be a better solution? because <insert reason>". I'm sorry but if you're a functioning adult working in a professional environment, you should expect to receive critiques and feedback on your work. If someone is so sensitive that they cannot accept constructive criticism on their work, I don't know how they're ever going to learn or improve.
