I like to avoid religion and politics here but this one statement applies to both equally.
If you are in a room and the man standing up front "preaching" to the faithful, be it a church or a political rally or another type of meeting. and he's preaching: Those people are just animals, and those people do not deserve to live, and those people should just starve to death, and those people should just die.
YOU ARE IN THE WRONG ROOM.
For the commandment is to Love thy Neighbor.
And when it comes to Police, Fire, Military and so on.
Well it is written that No Greater Love has any man than to lay down his life for a friend.
And though that is in the Bible. it's not true.. because Police, Fire, Military and the like. lay their lives on the line for people they do not even know.. Myself included. and for that reason folks.. And that is perhaps an even greater love.. And the commandment is to love they neighbor.
And before you ask EVERYBODY is your neighbor.
