Downvotes for an attempt at constructive suggestions. Fly that proud introvert flag, HN!
That's really not OK in so many situations.
Then I went on to make what I considered a positive and constructive suggestion, that assuming I did not understand the person, he might look in places other than zero-population areas for suitable but more convenient habitation.
I'm sorry you see that as "not OK." I see it as ridiculous that this sort of well-meaning input should somehow be so awful as to be unmentionable. But I seem to be pretty much alone there.
I see no reason for you to project your standards of mental health onto other people, even if you don't share their inclinations.
You like being alone. Congratulations. So does he. That's great, and I never said it wasn't OK. I tried to make suggestions that people for some reason didn't appreciate; that doesn't mean I was condemning him or his lifestyle (or your lifestyle).
Anyway, this is past the point of productivity. I tried, no one appreciated it, and I'm not going to apologize for other people's uncharitable misinterpretations.
