No one advocates for medical changes beyond (reversible) puberty blockers at that age - specifically to give young people time to figure these things out. Also counseling is often involved, so in your daughter’s case it’s likely a professional would have worked with her and helped her determine this about her.
This will only make actual antisemitism (the kind you describe) worse. The authors of this letter are telling Jewish voters to abandon any principles they have regarding their own country - it doesn’t matter if you support abortion rights, believe in funding public education and social welfare, or just oppose the Trump / fascist agenda. None of that matters compared to supporting Israel. It’s the antisemitic “dual loyalty” trope come to life.
There are well-evidenced problems, sure. But what these governments think are the well-evidenced “problems” versus what you think they are, are two very different things.
The proposition for a one-time tax on billionaires, while I hope it does pass, is not the most important prop in this regard. If for no reason other than it’s just a one-time tax. The counter-proposition to ban taxes on “personal property” i.e. wealth is far more impactful long term. We should be taxing wealth and not income. If that prop passes, California will never be able to tax wealth. And frankly I’m worried it will, because Americans just have this reflexive “taxes bad” ideology and will vote for it thinking it means the state will never be able to tax the $15k they have sitting in their Roth IRA or whatever.
