Its probably a lot bigger than any single chemical or deliberate attempt. Especially as triggering puberty earlier is antithetical to most of their goals, whether pedophillic or tranny.

Not necessarily, earlier puberty will also mean more years before turning 18 that they'll be seeking out sex so it will be even harder to find a woman who hasn't been slutting around and for boys it means more years of being horny before they're able to start working to get money to be able to attract a woman so there's a higher chance of them resorting to some form of faggotry.
