Do people expect 13-16 year-olds to be more resilient to bullying than younger kids? Are they?

I’d expect that to be the most vulnerable age, but I don’t know. 17-18, I can see, but only because they’re more likely to have more varied social circles, and may be able to find more accepting groups on their own (though that could be a dnd group or an alt-right group, so that’s not necessarily a good thing). Again, I don’t really know anything about childhood development though.
