Dunno, never knew much about that stuff. Did not see much of sister’s kids after they were 5-6 years old. Took my wife to clue me in when they were in their twenties and she first met them.
The emos are basically the Beta/outcast types who were prime territory for recruitment. So they were recruited. You had bands like The Smiths and their gay frontman Morresy making it cool and one thing led to another.
Just a guess but having grown up in an alcoholic/broken family, ( I grew up in one myself) I could easily see your nephews being prime targets for such recruitment.
Which is of course, the only gays can ‘propagate.’
