That's how.
Him and people like him have no business being around children. None. He doesn't care how much harm that it does to these people's lives, so long as he can find a link which tells him he's self-righteously right. So long as he can call his evil righteousness.
He's not right. There is no scientific evidence showing that "transitioning" Children improves their outcomes, ample evidence they are doing serious harm to some of these kids. The doctors are committing malpractice, violating the Hippocratic oath of first do no harm. The parents are naive, negligent at best, suffering from their own mental illness at worst. "Educators" like Sam and proponents of their ideology are complicit in this great evil which ruins the lives of many Children who cannot consent, simply cannot possibly make an informed decision with full appreciation of the ramification$.
How we as a society allowed this to happen over the last decade or so is really something else... a real case study. That there were not enough people of integrity, gumption and genuine moral fiber to stop this abuse of children from happening is a real indictment on our civ.
