And as a person with autism I could argue that you were tricked by your brother utilizing his trusted status. The words themselves weren't enough to trick you, but coming from your brother they were. Unless you would have believed the same outlandish nonsense regardless of source the issue wasn't with the words.

But we're fussing over semantics here. I don't care for the phrase "easily tricked by words" and don't identify with that experience. But I don't care if you think you do. Carry on!
