It's so easy to hold into black or white worldview.
Our lazy brain likes this simplicity.
If he's not supporting X than he's definitely with Y.
In fact every situation is black, white and every gray in between at the same time.
Discussion
People have been conditioned to see some things that binairy, a few examples:
Democrats - Republicans
Like - Dislike
Black people - White people
With other things they're spinning it the non-factual way:
'Sex or gender is a spectrum'
'It's global warming, ooh wait now it's climate change'
'Dollars is money, bitcoin isn't money'
The world isn't black, white or grey, it's colourful, pay attention to it and it will enrich You! 😉
