it's not disrespect, it's a very common experience which is why people say it so frequently. But i have also encountered lots of religious folks who misunderstand the truth as disrespect. Maybe you did actually read the bible and not just selected verses from your leader or franchise but if you did and maintained your faith that's somewhat unusual.

and there were christians fighting to maintain the institution of slavery just as the only good white american fought to end it. and instructions in the bible about how you could keep a slave you were otherwise supposed to free under jewish law. Surely you can forgive us having a low opinion of a text that can be on either side of the "debate" about slavery.
