I’ve absolutely had someone blow a gasket over asking for clarification when they wrote a few sentences where it was unclear from their statement whether they were progressive or a white power lunatic. I could have assumed but my level of certainty was hovering in the mid-50% range. Sometimes the author is an idiot and the questioner is justified. EDIT: from what I could figure out, the gasket blower has a habit of assuming you know their post history rather than letting each comment stand on its own. Which is not very smart.

We have people who think that ‘e-mail’ gets an s as a noun - ever - when ‘mail’ never has.

They will be confused that the sun keeps rising.
