I don't trust any media spin.
Let's go to the video.
She DID say it is against the law to threaten members of congress.
Anything else? Yeah, she is being hyperbolic.
If anything she's understating. Have a look at the image in my last link to see what "making fun of" actually refers to.
"Threaten" in this context means "rape".
Kudos to
Care4all for doing the sleuthing that the OP should have done in the first place.
I don't think that qualifies.
An ostensibly PRIVATE group would fall under the heading of correspondence IMO, IOW, not public. But, I am sure this is up to debate.
I would have to read the TOS of the group.
For instance, in terms of, like, snail mail. . . if the same image were published in a satiric partisan magazine? However revolting and disgusting, I don't think there is a court in the land that would lift a finger to move against such a publisher. Both figures, by fact that they are public figures, and the image is meant as satire, or subject to satire. Folks that subscribe to such a publication opt in, as it were.
I'm not an expert on libel and slander laws, but they apply differently to private and public figures if I am not correct.
On top of this, these posts are not meant for the general public.
