Just as love comes from satisfaction, hate comes from frustration. Hate is as useful as love, and it often works a hell of a lot quicker. Hatespeak is usually more honest than lovespeak, and it s always better than doublespeak. Some things seem worthy of hate. People hate being told lies, especially when they might die because of those lies.
People hate when others are indifferent to their situation.
People hate when they realize they re being robbed and can do nothing to stop it. Poor people hate, while the affluent show disdain. The powerful have always regarded the powerless with a supercilious contempt that could very rightly be called hate. So they re in no position to act holy about so-called hate speech. The MOST important type of speech to protect is hate speech, because it often contains desperate truths that would lose their urgency if expressed calmly.
