You're kidding right? The bible was used as justification for slavery and for preventing interracial marriage.
Why the Ugly Rhetoric Against Gay Marriage Is Familiar to this Historian of Miscegenation
It was a wrong interpretation used for political gain, as the bible has been misused before, notably in the middle ages as a reason for the feudal system and serfdom.
Show me where in the bible that it says it is OK to be a racist. The one place you MAY find it is in the earlier OT, and those were based on the rules made by a small ethnic minority (the hebrews) trying to preserve thier way of life, not some technologically superior group of people turning less technically proficient people into chattel.
On the other hand, prohibitions against homosexuality are found in both testaments.
LOL...the only part of the NT that discussing gays and lesbians is not talking about loving, consenting adult relationships. Not only that, it was the likely closeted St. Paul that was talking about it.
What has Jesus said on the subject? (is that crickets I hear?)
Funny that you would say that the OT is about "preserving their way of life" but that the NT was for the more "technologically superior". It's been about 2,000 years since the NT. We're even more "technically superior" to the men that wrote the NT. Racism...bad. Homophobia...bad too thanks to our "technological superiority".
