Wow, so it fell right after becoming a Christian nation<quoted text>
rome was only official a christian empire from 325(constatine) until the visigoths sacked rome in 410 ad.
only 85 years
well there are different theories as to when the official fall was, but 85 years before the fall, yeah that could make the case as the cause if that is what you wanted to do.
More than accepting of homosexuals by this christian empire anyway
