I can imagine she felt helpless when her work was being blocked. Imagine you were going to start a project and was told someone in your org was against it and that you couldn't do it as a result.
Maybe take a step back, consider the possibility that you may be wrong, and if you still think you are right, then attack their ideas and arguments, instead of acting entitled and demanding to know who said this or that.
Like PG wrote, the worst thing you can say about an idea is that it is wrong, you don't need to resort to personal attacks or x-isms.
