Your comment on climate change rings very true to me. I do not have an opinion on it either way, mostly because I have not done much research into it and I am not a lefty so I generally do not take stands on subjects I know nothing about.
But whenever I am confronted with someone lecturing me on my apparent need to consider climate change to be the greatest threat to the planet in history, I usually just ask them to explain how they know that. I also ask, given that we know that the earth has been warming and cooling in cycles for millions of years, how they know with such absolute certainty that this latest cycle is down to human activity.
They always respond, just like the poster here responded to you, with a lot of childish ad-hominems.
