that we would have to pay attention to what the source of our fear is
I always check out things we are defending or protecting, that's often where the fear is coming from. A lot of times we can be irrational. But we end up defending something we find close.
Often defending things in culture, that perhaps we should actually let go of. Culture changes naturally, regardless of whether there are external influences or not, because the environment changes. Defending what might no longer be relevant, is silliness.
