I don't even believe it's traumas. Most hatred is born from lack of experience and therefore empathy. The trauma they claim is usually fantasy, to feed into the mentality that they are right to be afraid. Like the whole oppressed Christian rhetoric I was fed at an early age, it doesn't exist in the US. Pray to the guy on the cross, I won't stop you. Just don't him as an excuse for causing harm to others. You can practice your religion, but it shouldn't stop others from living their lives without fear or harm.
