Not trying to be funny, either, but how could an isolated population, of a severely remote/xenophobic island, not just disappear due to the side effects of inbreeding? Do secluded populations eventually become immune to the mutations?

They may be experiencing horrible effects from inbreeding as we speak. I think it is probably important to point out that they dont seem to have retained boat technology (extremely strange for island dwellers). It is also speculated that they have lost the capacity to make fire (fire is considered a human universal).
I mean, no one can say for sure but if both of those things are true I think it is safe to guess that inbreeding has wreaked havoc on those poor people.
Small population groups who are in contact with the outside world, like the Samaritans, are documented as having strong traditions as to who can marry whom. Likely these island tribes do as well
The inhabitants of North Sentinel island are not *entirely isolated*. They regularly engage with other tribes on nearby islands, including for events like marriage.
As such, there is no risk of inbreeding, since there is a large enough population between the tribes to be sustainable. The difference between the Sentinelese and these other tribes is that the Sentinelese have decided not to engage with people outside their “knowns”, a decision accepted by the government of India.
They are, shut off from people not belonging to the tribes the Sentinelese have always known.
My family has an odd pairing.
Grandma me grandpa and got married
Her brother met his sister and got married.
So when you say it to people it sounds strange, but once you explain it it’s pretty normal.
“My grandma and grandpas brother and sisters married each other” sounds weird. But once it’s explained it’s normal.
