> That doesn’t mean you have to take abuse. But even if someone is unambiguously disrespectful (e.g. name calling) you can generally be respectful when pointing that out or simply not respond.
Simply not responding leads to this person bullying you and/or the entire team eventually. Unless this happens really once, which in my experience now is not the case. Some people are just bullies, not the type they come and hit you in your face, but do snappy comments, or shaming you, etc., and they should not be allowed to continue with their behavior. If your manager doesn't do anything about it, you have to do something about it. It takes bad experience to realize that, but once you understand "the game", you will never let this happen again. Just learn to distinguish between personal attack AND "PR comment" on your code, though.
