Well, that’s quite a bit of baggage to unpack.
In regards to “miscegenation” we have Galatians which largely renders that point moot, highlighting everyone’s love of cherry-picking scripture.
In regards to homosexuality, you have Leviticus, I assume you’re referencing. Given the widespread practice of man-boy relations as famously highlighted by the Spartans and of course recent special military operations in Afghanistan I have an incredibly hard time believing this piece of scripture is at all misinterpreted.
Regarding BBQ, I assume that’s a presence to kosher law and subsequently an attempt at calling hypocrite on the congregation. In that regard we have quite a few pieces of scripture, e.g. in Mark, effectively redefining and negating much of kosher law thereby making that issue moot.
Overall - your assumption around Southern Baptists largely stands. Our last church, my wife had to constantly deal with snide remarks because of her having previously been married to a man that went and overdosed on fentanyl. Meanwhile half the grandparents in the congregation are raising their own grandchildren for the exact same reason…
Which leads to our currently being “unchurched” as they say, because the worst part of Christianity is the other Christians ;)
