Not too far off… I work in orthopedics and rehabilitation and my specialty is kinda famous for being really bad at having families.

But I’d say the underlying cause is more like undiagnosed personality disorder/autism than being patriotic. Most of the older guys are extremely divorced dads who are obsessed with squash if they are brown or golf if they’re white. We also have divorced dad “pretends to be cowboy or in motorcycle gang” if they’re a younger boomer.
