in fact it increases it because people become even more resentful because their freedom of speech is limited. Most developed nations have laws regarding 'hate' speech or writing and this is fine. But to divide it up into something particular for Jews or Muslims or Africans or Asians is ridiculous. Most people are not anti-semitic but many people in many cultures, religions and nations are racist, including Israelis and Jews. The Jewish religion is inherently bigoted because it teaches that followers are special, superior and chosen. Israelis are particularly racist toward Palestinians in particular and arabs in general as one finds visiting that country. A society is as bigoted as the culture, religion and society allows and usually it is sourced in fear. Censorship of speech does not change this.
