As we mourn once again for the Beis Hamikdash and lament our physical and spiritual distress as individuals and as a nation, we wonder "why?".
Well, we all know the gemara that the Beis Hamikdash was destroyed because of senseless hatred. But people miss a point in the gemara. What the gemara says first is that despite the fact that the Jews were involved in Torah and gemillus chesed, nevertheless they hated each other.
They performed chesed and hated each other??

That isn't how I treat MY enemies [hope I don't have any but if I did...]!
This is HUGE!
Hashem doesn't just want us to be "nice" to each other but to genuinely love each other deep in our hearts.
HUGE!
