First, you don't know if that is what originally was written. Second, I could easily interpret that as "don't go to sleep with another man, but having sex is fine, being in a relationship is fine". Or, since it actually says, man shouldn't sleep with a man as he does with a woman, then it can easily be interpreted as "if you like women, sleep with women, not other men, but if you like men, you should sleep with them not women". Or it could also mean that you shouldn't deny your attractions. Plus, how long does that apply? Who gets to decide which men it applies to? What about hermaphrodites? Are they considered men or women in the eyes of the Bible? And what about eunichs? Should they lay with men or women? Also sounds like it is just fine for women to "lay" with other women, so lesbianism is not violating that passage at all, no matter how you personally interpret it.
Oh there are so many more things here. The point is absolutely that it is subjective. Why do most Christians no longer abide by many things said in the Bible such as burning witches or those who profess to be such or that women should keep their heads covered in church or not hold power over men or not teach men, especially on religious matters? Why are those passages not being brought up here as part of the interpretation argument?
