This "struck" is translated as "fascinated", and it seems so, but what do you think?
ex)The behavior of young men and the preferences of young women are evolving. "I was struck by the younger people's ideas," Professor Jane Pollins said. "They prefer thoughtful men who have actual competence to peacefully resolve conflicts - very different from the kind of tough men who were once seen as the ideal," she said...
To me, it means "surprised" or even "very surprised" more than "fascinated."
