Realistically they have no idea what it's about either way at that age. It's just a colourful parade. they have no idea what it's about or what a sexual relationship is at that age. The idea that children are "born with a gender" is quite obviously nonsense as genderised traits are arbitrary and social-defined, and the science is inconclusive on sexual orientation but (IMO) not really all that relevant... whether sexuality is ingrained at birth or develops over time, it isn't (or shouldn't be unless something is very wrong) present at 4 years old.

Kids are just kids and any attempt to make them "part" of LGBTQ is something being applied by adults. That shouldn't be happening, but if they're just there as observers? I don't see anything wrong with that on balance.

So long as it's not a full adult-style parade where sometimes people are not fully dressed.
