Hateful words are nothing. They can be ignored and left to disappear into thin air. By choosing to ignore, the speaker often becomes embarrassed because he did not get the reaction he was looking for, and rethinks his reasoning.
But hateful actions are of a different matter. Actions are real and tangible, and actions always have consequence.
It is hateful actions, as humans, that we need to rebel against. And as humans, it is hateful words we should ignore and walk pass, so as not to stir actions. Be the better man.
