My issue with kill all tieflings attitude is related to the rules of this world as I understand them (and as very patient forum users explained them to me). If we know that in FR there are inherently good and inherently evil beings, but there are those that aren't (like the php races that could have any alignment). If you arbitrarily decide that because X percentage of tieflings are evil all tieflings are evil, why not apply this logic to all other races that are not inherently good?
