It's so easy to do, to identify "them". Those not like us, those from that other "tribe", those we look down on, the enemy.
I am as guilty of this as the next person and can slip into demonising managers, IT, and those who don't "get" the internet or technology.
The next step is to devalue those others, to dehumanise them, to find reasons to reject them, to exclude them and at our worst to justify killing them.
But there is only us. There only ever was. I for one am going to try harder this year to remember this.
