The Sedition act was not popular and is considered an historic relic best left alone.
None. None whatsoever.
You, I, and everyone else here are nothing to these people.
>>What reasonable action(s) can be taken? <<
All we can do at this point is continue to educate people in a reasonable and calm manner pointing out what in fact is happening. Blogs, e-mails, group discussions, support people who tell the truth.
Remove the incumbents when election time comes.
Hold your local officials accountable for everything that they do right down to your town supervisors, mayors, superintendents, County Executives in short ANY elected official.
If they violate the law, make a stink about it on a local level so that they can be removed from office asap.
Stay informed, and speak out while we still can.
