I've heard of Kristen Stewart, but only the actress, not the scientist. I assumed the same. "Ah well, suppose that must be a common name."
Thank you for the condescension. It was a request for clarification in the title.
I am sure there are plenty of people whom I consider "conventionally famous" whom you've never heard of. That doesn't make you an idiot.
There was no request of any sort in your comment.
A request usually implies a question. You didn't ask one. You simply stated you didn't know her. Your post was actually far more condescending as written.
