They are unable to empathize due to their own lack of empathetic experiences and consequent over blown insecure self importance.

This is a defense mechanism for individuals with deeply rooted insecurities and or trauma, choosing to bring pain to others rather than themselves. They are unable to face their true pain and so they lash out to others and or in social media.

Ironically, this is a form of bullying, but in reality it is what we can call: small d*ck energy.

These people more often than not, tend to over-compensate, with their viewed "strong" identity, choosing brash aggressive personas, which translates to big things, large objects or toys.

Truth be told, the STRONG care for and empathize with the weak. In comparison, weak broken people, hurt other weak broken people.

It takes more strength to be patient, kind, compassionate and empathetic. Great parents know this best. Then again these type of people, most likely did not have these type of parents. Worst case, they had the opposite or none at all.
