A lot of those are technically not true - the sky is frequently not blue, the sun doesn't actually rise and there are number systems where 2+2 does not equal 4 (eg, 2+2 = 1 in a mod 3 arithmetic).
That sounds pedantic until people start disagreeing or implementing legal requirements that result in people needing to use the definitions. Eg, if there is a legal requirement to recognise that 2+2=4, is it ok to teach modular arithmetic? Especially if someone has a grudge against the teacher. Lawyers are more than happy to punish someone over a technicality.
if it's any consolation, when the sky isn't blue, it's mostly because the ground is on fire. a situation which is exacerbated by anthropogenic climate change.
so i mean, it's hard to agree on the basics when the basics are changing, I guess.
