Prem dai, you are unnecessarily splitting hairs about "What does not kill you, only makes you stronger" by Nietzsche because it is so oft used that it has almost taken the form of an axiom. For example, if you were to say/write "To be or not to be" you would rarely mention Shakespeare unless it were in a Shakespearean or literary context. Therefore, it would be redundent for you mouth off at Ashu for this often used phrase. Plagiarism is a non-issue in this case unless he used the phrase in a psychological context. However, if you do have some concrete criticism on the topic at hand, I'm sure he'd happily humor your rancor.
