The assumption that this is inherently sex related is where the issue starts. This is why the discussion shifted from talking about sexuality to talking about gender nearly 20 years ago. Ideas like boys cannot wear skirts or play with barbies are present from a young age, yet we don't accuse people opposed to boys with skirts/barbies of thinking about said boys future sexuality.

Well it was the parent comment that was linking this to sexuality - Hetronormativity is inherently about sexuality (i.e. Hetro-Normativity - Hetro -> Heterosexual: of, pertaining to, or being a heterosexual person).
