I'm really sorry (not really) to inform you of this but...
No religion or spirituality gives you a valid excuse to be hateful, racist, bigoted or violent (without just cause for protection).
“Historically my ancestors were more violent and concerned with war”
“Mine is a holy war”
“My ancestors believed ______ about people from different races.”
“My ancestors had _______ for slaves.”
“This was the perspective of [religion]”.
You know what also used to be part of history? A Geocentric model of our solar system. Slavery. Child marriage. Rape. Not understanding why germs cause illness. Primitive and harsh justice sentences. Fear and mistrust of science.
But we moved past these things that held us back as a society. We EVOLVED. These things aren’t part of modern civilized nations for a REASON.
How the early practitioners of a religion behaved does NOT give you a pass or an excuse for your backwards prejudices. They are YOUR prejudices to work through or not. But no religious history gives you license.
