OK so unfortunately the web is full of crazy people with their zombie arguments, where loudly worded statements seem to drown out careful investigation into a subject. Particularly if it doesn’t correspond with your worldview. A good example of this is Climate change. Evidence for climate change caused by man is overwhelming full stop. Watch these two videos. Then try playing global warming sceptic bingo. There are plenty of deniers (comments in this article are worthy of reading carefuly) out their but read their sources and the way they have made their calculations and it soon becomes apparent how biased they are. Better we try to get on with fixing our own problem don’t you think!
