Indeed. Not always easy online too. Some are too easily triggered, others who can only articulate their ranting through verbal abuse from the get go, and worse, those so caught up in their own conspiracies backed by very little first-hand experience that they can’t separate basic reason from nonsense. Having said that, yes, we know quite a lot but also so very little. That’s why we humans naturally hypothesise, test, repeat, challenge, hypothesise, test, repeat, challenge in the never-ending pursuit of knowledge and that must always be conducted with an open a mind.
