J'ai hésité à poster ça ici ou dans le topic "féminisme", mais je pense que ça va au-delà d'un simple clivage hommes/femmes :

Si vous ne voulez pas tout lire, voici le cœur de l'article :

Me: What kind of intellectual climate do you want here at Centerville? Would you rather have option A: a school where people with views you find offensive keep their mouths shut, or B: a school where everyone feels that they can speak up in class discussions?

Audience: All hands go up for B.

Me: OK, let’s see if you have that. When there is a class discussion about gender issues, do you feel free to speak up and say what you are thinking? Or do you feel that you are walking on eggshells and you must heavily censor yourself? Just the girls in the class, raise your hand if you feel you can speak up? [about 70% said they feel free, vs about 10% who said eggshells ]. Now just the boys? [about 80% said eggshells, nobody said they feel free].

Me: Now let’s try it for race. When a topic related to race comes up in class, do you feel free to speak up and say what you are thinking, or do you feel that you are walking on eggshells and you must heavily censor yourself? Just the non-white students? [the group was around 30% non-white, mostly South and East Asians, and some African Americans. A majority said they felt free to speak, although a large minority said eggshells] Now just the white students? [A large majority said eggshells]

Me: Now lets try it for politics. How many of you would say you are on the right politically, or that you are conservative or Republican? [6 hands went up, out of 60 students]. Just you folks, when politically charged topics come up, can you speak freely? [Only one hand went up, but that student clarified that everyone gets mad at him when he speaks up, but he does it anyway. The other 5 said eggshells.] How many of you are on the left, liberal, or democrat? [Most hands go up] Can you speak freely, or is it eggshells? [Almost all said they can speak freely.]

Me: So let me get this straight. You were unanimous in saying that you want your school to be a place where people feel free to speak up, even if you strongly dislike their views. But you don’t have such a school. In fact, you have exactly the sort of “tolerance” that Herbert Marcuse advocated [which I had discussed in my lecture, and which you can read about here]. You have a school in which only people in the preferred groups get to speak, and everyone else is afraid. What are you going to do about this? Let’s talk.
After that, the conversation was extremely civil and constructive. The boys took part just as much as the girls.

Ce côté "tout le monde est égal, mais certains sont plus égaux que d'autres" est assez inquiétant, je trouve. À noter que dans les commentaires de l'article, il y a des témoignages d'élèves qui étaient présents ce jour-là (certains qui vont dans le sens de l'auteur, d'autres non).
