Thanks for being reasonable, even though we have differing views. That is a rare quality around here.
Anyway, to answer what you said, I was talking about Genesis chapter 8, verse 21, which is the end of that chapter... so that's why I said it's just a few verses before chapter 9 scripture you mentioned.
So, according to the order of events, shortly before God gave mankind over to our selfish desires due to our hardened hearts, He said "I will never again curse the ground for man’s sake, although the imagination of man’s heart
is evil from his youth"
Yes, Noah found favor with God, but you have to keep in mind that the rest of the world at that time was horribly evil and violent. So in comparison, Noah was not a bad person. But that doesn't mean Noah was perfect or always did the right thing. We know that because not long after that, Noah got drunk, so obviously he was not always doing the right thing.
As for the last thing you said about a thread on the topic of biblical vegetarianism, yes... that's a good idea. I fully admit I'm in a very tiny minority among Christians with my position... but there are 3 or 4 of us here on this site who are Christian vegans. I think it's always an interesting debate, when the topic does come up.
