Yes, all these 4 statements would fall under hate speech laws in France.
And yes, people have tried to turn these prejudice into eloquent pages with precise terminology or into stand up comedy and have been shut down for it.
Shockingly, France is not a den of conformism yet. It is in the US that Charlie Hebdo covers are censored and where people "agree to disagree" instead of exploring their disagreements.
What definition of hate speech are you using and what event does it apply to?
On a related note, here's some statements that may or may not be hate speech:
1. Africans are stupid and criminal, we shouldn't let them into the country.
2. Transsexuals are crazy people. They need medicine, not coddling.
3. Muslims have evil beliefs and blow people up and I don't want them in my country.
4. Homos are unnatural, spreading disease and sickness. We need to keep our children away from them so they don't catch the gay.
I've written all four to imply a large amount of ignorance and strong emotional motivations, but they are nonetheless a crude attempt to express a public policy and a reason for it. Should they be banned?
Should they also be banned if written in the form of an eloquent 80 page paper with precise terminology, strong citations from numerous studies and polls and a grounding in commonly accepted principles in political science and ethics (assume such a thing were possible)?
