There are established “truths” that became impossible to question, or then the one who dares doing so will be declared:

• a negationist (that attributes to him a nice smell of hatefulness, similar to anti-Semitism);
• sold to a neo-liberal and slave driving capitalism, of course neocolonialist or otherwise imperialist;
• or, in a condescending tone, being oblivious, what is even worse than the first two categories, because in the asylum nobody worries anymore about your reason.

Here is a not exhaustive list of these received truths, similar to increated religious texts:

• Nuclear wastes, dangerous and impossible to dispose of in a stable, long term way;
• Synthetic chemicals, creating monsters that come out of the flask;
• Genetically modified organisms, against nature;
• Electromagnetic radiations, at all intensities and frequencies;
• Pesticides, serving only to enslave the farmers and to poison the consumers;
• Fertilizers, bad if synthetic, good if organic;
• Biodiversity, to be fully preserved on every square meter of the globe;
• Organic food, because “naturally produced”, without any productivist spirit;
• Fair trade, which corrects terrible disparities and absolves the West of its sins;
• Man responsible for the climate and its disorders (sic); by respect, I spare here the woman;
• Finance with its overwhelming Mephistophelian aspects;
• Consumption, always exaggerated if by the other ones;
• Future generations, which need our solicitude because, of course, they will be more incompetent than us.

Expertise and nuances no matter anymore, we just have to have an opinion.
