As a man with adhd, I do this all the time to men and to women, and I've been accused of mansplaining. I'm working on it, but I promise it has nothing to do with sexism. I just think everybody needs to know all the details so rhey can reach the same conclusions as me.
And for what it's worth, I really appreciate when someone does the same for me on a topic I don't know about. But I understand how frustrating it is when someone does it on a subject I do know about, so I always try to gauge knowledge before info dumping. What catches me off guard is when someone isn't interested in learning. They don't know everything, and they are just OK with walking through life, knowing they don't know something.
Point is, I really do appreciate the grace presented in the post. I don't mind if you're being condescending if you forgive me for oversharing.
