A story that is much bigger than it may sound at first blush. The goal of this con game from the start, late last century, was to marginalize skeptics as "deniers." It's origin has been forgotten but the intent was to compare global warming skeptics with Holocaust deniers. There hasn't been global warming, man caused or otherwise, for 15 years. The global warming crowd is growing increasingly frustrated with this reality and growing more desperate.
If they can't marginalize critics it appears they will silence them. Yes, it's Reddit. But others have either done or proposed the same thing. Global warming fascism is having a chilling effect on free speech.
