See my other post. Hate speech laws are actively used in Germany to manipulate political campaigns. The legal process has been removed and private organizations close to the government get to decide what's hate speech and what's not.
And that's exactly the problem with it: It cannot be clearly defined and everyone is offended by different things, which makes it a perfect tool to censor just about everything you want.
