A stick of
candy dat you bribe someone with in order to keep him from being "convinced otherwise" by one or more fellow
humans who might try to get him to
change his presently-in-agreement-with-you viewpoint.
Anti-
sway bars can indeed sometimes be an effective way to keep someone "on your team", but it can also prevent said person from honestly pondering a particular topic or issue and then forming his own unbiased
opinion about said subject, similar to how main-stream
religion often does.
