The words are not meant to convey meaning, they are weapons, meant to disrupt you. If other words or the opposite words disrupted you, they would use those. The trick is not to look past the words at the speaker: Why are they saying it? Who does it benefit and how? The words themselves are meaningless; they are wadded up pieces of paper thrown at you; they are as meaningful as text printed on a bullet aimed at you.
So have heart, the people are not crazy. They don't believe those things, they just are tactically saying what is most disruptive to you - which in part is done by making others think they are crazy beyond control or reason.
