I would bomb their cars and houses with Napalm. I would bomb the basements, I would shoot the thread-hijackers and their enablers just as I would a traitor in wartime.
I would poison them like they deserve, and I would force feed them large quantities of heroin. Would they die? Who cares?
These people are ruining good discussion and debates. Abusing the First Amendment. These people are destroying good threads. Torturing them. But I would turn all thread-hijackers that are caught lose, with a stern warning that the next time they do it they get executed.
War is war, fight it like a war or STFU and get out of the way.
Good Move. Hope it works.
