Not even being provocative but if you think Greta Thunberg has the maturity to guide global policy-making then you cannot object to Jeffrey Epstein paying 16-year-olds for sex.
I value consent! If the 16 year old did not consent, then this is terrible. If she did consent, then I don't view it as terrible. I don't have enough information to know how much she consented at the time. To be clear, it's plausible that she was coerced, I'm willing to buy it.
