I know of no 'climate denier' who thinks that the earth is flat. 'Flat Earth' is a psy-op developed specifically to associate with people who don't go along with the corp/gov line on such things as 'global warming', 'vaccines', etc.
Ahahahahahahahahahahaahahaha.
Global warming deniers == vaccines deniers. It's your words, are you?
I have one interesting thought in my mind: If some people denies the fact of global warming which is not denied by any famous scientists...
When a scientist says that he does not deny global warming, that does not mean that he agrees with alarmist or politicians or common people's brainwashing on what to do, if anything, about it.
The one thing DOES NOT LEAD to the other.
