Don't forget that troonery is also an important weapon in the fight to destroy the idea of the family as a unit with biological bonds. Think about:
"Love makes a family" "Families come in all shapes and sizes" "My wife might have carried my children but I transitioned and I'm a woman now so I'm their mother, because "mother" can mean anything!" "Parents don't have a right to control their children. Children have rights and if a parent denies their agency it's child abuse." "Children with abusive families can be welcomed by new, glitter families!"
What can be achieved by weakening or destroying all narratives related to biological bonds? We're seeing it already.
1. It makes it easier to push surrogacy. Since there's no inherent or sacred "link" between a mother and a child, it's all just an idea, then it's not wrong or weird for gay men to hire women to gestate babies for them.
2. It makes it easier to push biomedical and transhumanism experimentation, since gestating a baby is really a thing that anyone can do, and shouldn't transwomen have the chance to be mothers too? The ultimate aim was probably artificial wombs.
3. It will eventually make it easier for governments to take children away from parents who are "abusive," with an ever-widening definition of "abuse" that includes any actions that don't align with government propaganda. Families aren't real, remember, and love makes a family, and bigots obviously don't love their children. So it's
not horrific for the local team of government HR ladies to come and take someone's children because he questioned the necessity of a drag queen show. They're just protecting the kids from abuse!
The end goal here isn't to steal children (that's just a bonus), it's to keep people 100% in line and crush all dissent, since the government now has the power to easily take your kids if you do anything but clap and smile for the regime.
