I hate the phrase “climate deniers.” It is so utterly stupid; no one in the world denies that we have a climate, and no one denies that the climate changes over time, yet the left - so eager to nitpick Trump’s exaggerations or misstatements - routinely repeats this asinine claim about “climate deniers.”
Just toss these on them and tell them to get back to you with the answers:
1. Define the “correct” temperature range for the planet.
2. Define the “correct” humidity range for the planet.
3. Define the “correct” mean sea level for the planet.
4. Define the “correct” amount of precipitation for the planet.
5. Define the “correct” makeup of the atmosphere.
6. Define the “correct” amount of sea ice at the N/S poles.
7. Define/explain past glaciation and subsequent warming without any input from humans.
Deniers like Racist is the argument aborting epithet. Say one of those words stridently ends any conversation about anything in which he who utters them is at a factual disadvantage. Those words eliminate the necessity for any facts or knowledge. A few centuries ago the magic word was “Witch!”
I like to piss off liberals by calling them biology deniers whenever they start prattling on about how gender is just a social construct.
