Since when do Americans have to give the government an explanation for why they “need” something? If that’s the test, I can think of a whole list of things I don’t know why anyone needs.
I don’t know why anyone needs to burn an American flag at a protest. The point could be made just as well verbally.
I don’t know why anyone needs to read about the private lives of celebrities. Why can’t we shut down the gossip rags?
I don’t know why anyone needs to vote. One vote has never made a difference in any federal election.
I don’t know why anyone needs to bicycle in a city.
I don’t know why anyone needs to have anal sex at a bathhouse. I won’t stop them, but I don’t know why anyone needs to do that.
