"Uncle Will" was a homosexual, but a closeted one. As far as I have been able to see from biographical materials, Uncle Will never practiced his proclivities except when he was on foreign vacation jaunts --- he craved "handsome Aegean youths" --- and (anonymously) publishing a book of Uranian poetry.
I'll grant that Uncle Will did very well by his three adopted nephews. But I would have a different judgment if he had had a steady partner or multiple revolving partners, or if he had disclosed his sexuality conduct to them before their adulthood.
In order of preference:
1. Married loving parents (one of each sex).
2. Loving single parent.
3. Loving parent with long-term gay partner.
4. Loving parent with many/changing partners.
5. Unloving parent(s).
6. No parents.
7. Aborted.
