What if you are an experienced engineer talking to another experienced engineer ? Seems to me if someone writes bad code when they SHOULD be writing good code, code-shaming might be in order. I'm all for being nice and understanding. Everyone programs at a different level and I may not write code that is as good as I think, but some code is just obviously bad...and constructive criticism (if willing to be accepted) might help
