I like opening a can of worms now and then! I know what you mean. Awareness is essential and people are often switched off to the plight of others. I guess a degree of awareness stems from parenting and the society in which people are bought up. If the people around kids are switched off, the likelihood of the kids being aware lessens.
I believe humans are wired to connect with each other and cooperate, though. We survive best when we are in groups and helpful. Emotional anesthesia isn’t permanent, people can thaw out! But, yes, their awareness must grow. Raising the issue is useful even if it wakes up just one person. Thanks for engaging and bringing up an important point.
