The OT I think had 14 or 15 statements, but even in there, you are quite right that there is no commandment that specifically prohibits homosexuality or says that it is a bad thing. So rest assured plowter, you can be homosexual without worrying about the 10 commandments.
The 10 Commandments are another engima, whose purpose and very existence have been passed down through the millennia, allowing souls to believe in a god who would seek balance and light in our human experiment, yet by the very nature of our creation, duality, could never be achieved!
There are some unpleasant things in life, yes ...but to describe a poor meagre shellfish as an 'abomination' is a quite ridiculous! What about a baboons' backside...that's a lot less appealing than an oyster but you don't get him calling that an abomination. What was it that drove his hatred of the shellfish I wonder?
