Anti-science views in the left

[buritobr]

Usually, the biggest threats to the science come from the right. Many conservatives dislike the Theory of Evolution because this theory contradicts religions. Many conservatives are global warming deniers because conservative parties are supported by the oil industry. Most of the anti vaccination movement come from religious fundamentalists. Many "small government" conservatives dislike public funding on research.

But there are some anti-science views in the left too.
The belief that genetically modified food is dangerous for the health is not endorsed by the scientists. The belief that the human beings are herbivores by nature, supported by many vegans, is not endorsed by the scientists. Not all vegans are lefties, but many of them are. Although most of the anti-vaccination movement comes from the religious right, there are some anti-vaccianation anarchist hippies too. Concerning the anti-vaccination movement, Neil Degrasse Tyson has already said that both left and right have anti-science views.
We hear many people in the left saying that male opinions on feminism are not valid. This belief opposes to a racionalist society, in which we have to evaluate the arguments and not the people who are supporting the arguments.
Post-modern leftists influenced by Derrida, Foucault and Deleuze usually have some anti-science views.

Democrats are more likely to believe in astrology than Republicans.

I have a lot of left-wing friends who believe in astrology
