I'm fairly confident that I've never met a person who doesn't have ptsd. I think the division is really "people with ptsd that they can mask/manifests in ways that others can ignore" and "people whose ptsd can't be ignored by others so they're forced to begrudgingly acknowledge its existence"
"my cousin is the only one in our family with ptsd, he got attacked by a large dog and melts down at the sound of large dogs barking if he's already emotionally fragile" yeah and your mother shuts down at the sound of car engines that sound like her ex-husband's car, you just never noticed because you don't pay attention to her and she's been conditioned not to make her 'silly outbursts' anyone else's problem.
