It's not the mere existence of a person that's an issue, but rather the coercive, punishing activism that takes place around a false idea that human rights are at risk, while these personal choices are simultaneously being celebrated by nearly every government institution and major corporation in existence.
The same activism requires full acceptance by parents, families, and children who do not want these choices influencing their personal lives.
To say these rights are at risk is an outright lie.
It's one thing to have a significant voter base opposed to those choices and still be fully able to live and express those choices freely and publicly — while it's a whole different issue to have governments actively enforcing a different private life against their will (specifically LGBTQ folks).
