I agree with your list of What To Do. I think the best point is
refrain from engaging in black-white/binary thinking: either this or that - and no other way. 'Truth' is nuanced, there are innumerable shades of it.
There seems to be a tendency for people to say, you're either with us or against us. Well I am often with parts of the argument and against other parts!
by default, we polarize. if you try not to, you're engaging in critical thinking
Does that mean that black and white do't exist and everything is grey ?
