As you wrote it, yes it is completely fine.

Please back that up with links to a legal argument or SOMETHING. I realize it’s hard to prove a negative but can you at least back it up with authoritative links of some sort?

In the U.S., activities are legal unless there is a law stating that they are illegal.

We don't need to provide an authoritative link that the above is legal; you need to provide some sort of authority that it is not.
