I get to angry even thinking about it. Imagine your day job is to convince the public spreading poison globally is not dangerous only to make a marginal profit. And to give decision makers some excuse with some bullshit "proofs" that lets them stay "ignorant". Alot of enviormental issues comes to mind where this is happening today.
I've been astonished that so many people think it's okay. I think it's related to the tribal mindset, how cheering for your team has been more important in evolution than critical thinking.
