I live in a cohousing community. One of the folks in my community had a dad who'd been in HY. Super nice guy, glad I'd gotten the chance to have known him.
I asked him how he felt about HY. His take was that in spite of it having been mandatory it was a good way for a city kid to get exposure to the outdoors - and the leaders in his group were reluctant propaganda-pushers so it was easy to ignore that bit. It didn't seem to have damaged him.
I mention cohousing as he and I would see each other regularly at group dinners and potlucks.
