Presumably to the entity you intended to donate to, no? I would argue that determining where your money goes is a right.. If I intercepted all of your future charitable donations for my own purposes you would be understandably upset.

Great. So, stealing from charity is now ethical. Good to know !!!

Ha ha, so easy to refute. Is it unethical for the government to stop me from say, donating to a terrorist organisation? It's still "charity", right? ;)

if we really want to get dirty with things aren't you already doing that through taxes? black budgets and such?

also what constitutes a terrorist? its easy to say ISIS is terrorism, but are the truckers or January 6th people considered terrorists?

if so then BLM can be considered terrorists, and then how come they never got their donations seized?

deep rabbit hole with no way out

donation are purchases -- you are buying capital for the fund of your choice. if it turned out a charity you donated to was funneling money somewhere, they would be effectively stealing from you, as the thing you were purchasing was never given.
