If you have ever published anything anywhere then you are a journalist

[Benton D Struckcheon]

52. Whether you are or whether you aren't,

if what you're doing can be classified as speech, you are protected, far as I can tell:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

I had to look at it, and what I suspected is true: they didn't make a distinction between speech and the press. Speech comes first in the list, then the press, and both are in the same clause of the amendment. That would mean they thought of them as the same thing.
So, I don't know if this post makes me a journalist or not. It does constitute speech. Same thing. That law defining a journalist is an absurdity, and has no force: you're protected regardless.
Or would be, if our courts hadn't made such a hash of all this stuff.
