Except if trump doesn't want to disclose his taxes, he doesnt have to try to become president. We have good reasons for wanting him to submit, but all you have are some vague ideas of privacy and free speech. To be clear, your rationale is only an analogy for why he shouldn't have to submit them, cause neither privacy or free speech laws would prevent us from making submission of taxes a requirement
You are confusing what voters may demand with what government may compel. You should be perfectly free to refuse to vote for a candidate who won't release his taxes. That doesn't establish government authority to condition access to the presidency on surrendering private records. ‘He doesn't have to run’ is not a limiting principle. It could justify compelled disclosure of other stuff like medical records, school records, family finances or virtually anything else legislators claim voters would find useful. Next you will say government has no incentive to weaponize that information in bad faith. Good luck with that. Your american laws and Constitution are based on innocent until proven guilty for this very reason.
It's a system that only works with a moral society. The fact that you and others are pushing for a wholly immoral society where guilt is presumed before innocence shows the direction your country is headed.
The problem isn't Trump, MAGA, or TDS signalling. It's establishing a legal presumption that seeking public office requires you to prove your innocence by surrendering private records to the government. Once you normalize that principle, every lawful detail uncovered can be selectively investigated, leaked, or politically weaponized through legitimate channels. Government should need a particularized justification to invade someone's privacy; citizens shouldn't have to surrender privacy to prove there's nothing there. And a country should NEVER legitimize the weaponization of government against detractors.
