i would put limits on the freedom of humanity yes. the freedom of deliberately hurting, be it through words or actions, is the first freedom i would take away. oh look, we have laws wich already do that, fancy that.
freedom of expression does not, in any way, involve the freedom of showing you want more than half the world population eradicated, just for having a different belief or colour.
Then you are no better than a Nazi, really. They had limits on all sorts of speech and expression. I'm not surprised, really, given the comments in your sig. When are communists going to learn that forced progress made under the authority of the state is simply false progress and does little more than cause resentment?
"the freedom of deliberately hurting, be it through words"
this is especially vague, and extremely iron-fisted. First of all, words are not violence, unless they present an imminent threat of physical harm, just to get that out of the way. Secondly, what is the line here? "Hurt" in what capacity? Are you going to arrest an arguing husband and wife for saying "hurtful" things to each other? What if the words someone uses were not intended top be "hurtful," but the target of those words is offended anyway? Throw the speaker in jail?
