No definitive evidence, but it's a fair extrapolation, given his virulent denunciation of homosexual acts, in a manner that is quite hysterical.
If you want to take this approach, can you explain why he was even more 'hysterical' when it comes to husbands mistreated their wives (or vice versa); or slaveowners mistreating their slaves; Jews telling non-jews that they had to follow Jewish law if they wanted to be Christians?
As far as I'm concerned, Romans 1 is about the most 'hysterical' chapter in all Paul's writings (those that most intelligent scholars think he actually wrote). If you can't distinguish between the tone of the latter and - for instance - 1Corinthians 13, then I pity you.
Read Bishop John Shelby Spong's views - they seem fairly persuasive to me (a very interesting tome is "Rescuing the Bible from Fundamentalism".
I've read a number of Spong's books and articles over the years and find them rather tame. Can't say that they get anywhere near 'persuasive' unless one is pretty gullible; if anything, they are pretty second-rate.
As Bernard Shaw said "The lower mind cannot understand the higher mind". Spong certainly beats most of your effusions on here into a cocked hat. If you think he's so second rate, perhaps you might offer your views in a scholarly Christian publication, rather than adopting such a high-and-mighty tone here. I don't take an uncritical view of his writings, by the way - after all, I don't claim to be a Christian. But for someone like you to start throwing the word "gullible" about to describe those who don't agree with you, just about takes the biscuit. After all, you believe in a literal Resurrection, don't you? Something Spong is certainly not so asinine as to accept.
