>I don't personally know. but I do know that that "science" doesn't know either
Good place to start.
"Science" has become religion.
So, if they want their followers to believe something, all they have to do is add "Science says" to the headline, and idjuts gobble that shit up.
>they don't really know, but insist they do
Unfortunately, spot on.
There is a trick, though.
There are critical flaws in many of their fraudulent "theories".
Find the weaknesses. Not all are as obvious as others. But you don't have to be a genius to know that 2+2 does not equal 5.
It can be a little tricky trying to explain to others, especially because so many have several levels of severe brainwashing one would have to penetrate before making any substantial progress in a mind like that.
But don't let that get you down. Believe in yourself and build up your confidence.
Use your knowledge of their weakness to combat their narrative.
Example: "Science says global warming is not a myth"
Combat with: Then why is the Earth getting cooler, not warmer?
You can actually find images and graphics about this one, which is why I chose for example, because yes, the Earth is getting cooler, which is why they tried to switch catch-phrases from "global warming to "climate change", in hopes no one would catch it. We did. They are back-peddling. And setting forests on fire to "prove" their point. Gotta love clown world!
