That's true, I think it's human nature to get defensive when there's any personal element. Same reason it's ineffective to say, "you're wrong about X", but rather more effective to say, "the thing you said about X is wrong". If it's about the person that said the thing rather than the thing that was said (even if it's just the slightest whiff of it being about the person), even the most confident and self-aware brains can get super defensive without even realizing it.
