Gen Z - sees graphic things on the Internet.
Their great grandparents - fought WW2.
Every generation has its cross to bear.
Of course, but the point still stands, doesn't it?
When Gen X and Millennials used the internet, it was more akin to Tim Berners-Lee's original idea of an information-oriented interface. Nowadays, I'd hate to be just 3 years younger, because you get exposed to all sorts of lurid stuff at a young age.
That's my point - that 'squeamish' isn't fair, that there's plenty for us to be squeamish about if we wanted to but not wanting to watch animals die just
isn't the same thing.
The internet didn't start with Gen Z - we do have predecessors. "Yeah but war" isn't a real response to the argument I'm making.
(Another point would be that previous generations weren't offered the choice to not watch the film, in that scenario. I wonder how many would've availed themselves of it?)
Many people who look down on Gen Z looked down on the previous incumbent young generations. It's not about the characteristics that make this generational cohort distinct; it's about resentment of the young regardless of these factors. Barbs similar to 'they're squeamish' will certainly have been used to criticise past generations, too.
