Wise people know that there exists no individual aware of everything, possessing the key- answer to every question. In order, for the individuals, to learn and evolve, a free market of ideas must be created, where one contributes with one's ideas and where one changes one's mind or strengthens one's arguments influenced by other individuals' knowledge transferred to the market.
Laws restricting freedom of speech in the name of minorities' protection are, in fact, a way for the state to establish a monopoly of deciding which ideas are bad or worthless or even harmful. In order to protect individuals from them, it vanishes them from the market of ideas, which is no longer a free but a centrally controlled one.
State's sheer hypocrisy is demonstrated by the fact that it prefers to control expression, in the name of minorities, whereas it is unwilling to create a free society of tolerance and acceptance, in order to eliminate discrimination against them. Greece provides an example here: governed by a government unwilling to recognize minorities' rights (Muslims, immigrants, homosexuals are treated against the equality principle) considers speech-restricting laws an expedient measure, so as to protect those minorities.
