You are speaking for others - which is basically what the article is about. Judgment sucks and it's much easier than speaking your own truths - for example, do you have children and/or gone through birth?
That's speaking for the child. Speaking for someone else's feelings besides your own is speaking for others. And, it's not a perspective either, it's an opinion how someone else would feel in the situation, which is NOT a different perspective you can hold, given you aren't the other person.
Stick to what you know, is the basic lesson.
