Here is some solid advice....scan your attendees for probable government plants. Be especially cautious in chiming agreement to statements that are outright inflamatory and outright inciteful, especially if this person isn’t known to you and asks to ‘meet up’ etc. Watch this person carefully, and after they leave. Get their name and Google the hell out of them. If there is nothing on Google, be suspicious. Ask where they work, and what they do.
You can bet your ass the government is planning on stuff like this. They did it here in Georgia with a bunch of cranky old men talking out their butts who are now about to head for prison. Vetting anyone and everyone is the prime directive. If no one there doesn’t know them, then be cautious....
I second that warning...
