You are right - it would be best left to scientists. Real scientists- not the ones that argued for how many decades that smoking is not bad for you. Real accredited scientists- not the ones deemed good by believers in other creeds or those more simply manipulating opinion while laying the groundwork for evading their accountability. Who do you think is going to pay the price if the science, the real science- is right? Is your buddy Trump going to look after you when the fit hits the shan? Maybe there's a whole bunch of realists - really rich ones- already preparing for a future with fewer people, a lot fewer- in a world reserved for them by laying the groundwork for efficient population control measures. That is an entirely unpleasant thought isn't it?
