so why is the american government allowed to choose who to fund based on political speech?

is the first amendment written badly such that its only about negative things?

What the American government funds with tax dollars should be chosen by the American people, via Congress. Choosing not to fund speech isn’t the same as prohibiting it.

That said, “chosen by the American people” needs to be broad enough that we’re not singling out individual universities and individual countries based on the power of their political lobbies.
