Absurd. The libel suit would need to demonstrate that a person sharing the story (1) knew that the story was fake and (2) had a primary intent to harm the subject.
If the person sharing the story can reasonably assert that they had no way of knowing whether the story was true or false, they are innocent of libel.
If the person sharing the story can reasonably claim that they weren’t trying to assert the story was true, but merely trying to present what sort of content was being said about the subject, then their primary intent was not to harm, and therefore they are innocent of libel.
EVEN the people generating the news, if they can reasonably claim that their intent was clickbait, not malicious harm, they are innocent of libel.
The only people I would suspect might be charged with libel are those the Democrats don’t want to go after: the endless Facebook groups like “I F***ing Hate Republicans” or “Too Smart to Vote Republican,” etc.
The argument you are making is based on existing law, and would not apply under the new and greatly improved law.
Under this new law none of the defenses you have made would hold water.
