If there is one thing our world is not short of are examples that can be used to explain stupidity. A very generic example is that we have given humans guns (literally and metaphorically) and we have not taken the time to teach them how to use them. Another example is:

I had my temperature measured when entering a store and the store owner complimented me saying my body temperature was perfect after showing me the result. “30 degrees Celsius is far from being fever… Good!” I couldn’t help but pinch her to make sure at least one of us was alive.

The ignorance in matters of common knowledge doesn’t annoy me as much as people’s lack of interest in things that would affect them too.

That said, it could very well be that this was an epic troll and I missed on a good laugh.
