Quite technically, I'm pretty sure that discrimination is judging someone by a group they came from, usually before having any other evidence towards that judgment. If the group for sure (not just usually) always follows an attribute (EG: Retards are stupid) then I gueeeessssss that discrimination is technically correct. IMO, better usually not to judge a book by its cover.
My personally poise on religious arguments is that all religious parties are basically choosing to forgo logic and that's the point, thus religion would never hold in a court of law. Anyway, they will never convince each other. Since I'm here, I believe in unicorns and you can't prove me wrong.
Back on topic, if the atoms in a puddle happened to bond into amino acids and cascaded into life from there (basically the evolution/scientific origin theory as I have it) I don't see how that is mutually exclusive to creation. At this time we don't really understand atoms or where they came from, so you could attribute that to religion, but once upon a time people attributed lightning to religion so it's entirely possible that anyone who says god 'created' atoms now could be proved wrong later. At any rate, I figure that if you're changing anything in a religion aside from interpretation (especially how other people stand in regards to what your religion tells you) then you've proved that you're either choosing now or were choosing to believe for fact something that was wrong or made-up. It can only be concluded that what you believe in now will be changed later to be found wrong, or what you believe that was not the original belief is wrong. At any rate, your principals mean nothing.
...at any rate, any reason for people to be good to each other has a place in society, I suppose.
Also, inb4 god is an alien. Don't even.
