the turning on the lights on saturday refers to not working on the sabbath. you don't have any jewish friends i take it... there's even a whole industry devoted to making work arounds for ultra orthodox jews. how do you not know this stuff?
as to the rest. i'm not going to argue that with you. i would suggest you look into better translations, that weren't so political in nature than the KJV. there's been a lot of research done by actual scholar's on the subject. the modern notion of homosexuality is as foreign to biblical times as modern notions of marriage are. but two women in a long term monogamous relationship would have been so alien to the people who wrote those manuscripts that it would have not been possible for them to address it.
my big question i guess with this issue was always this. if god didn't want me to be gay, why did he make me gay? it's not something i just decided one day. i wan't sitting there trying to figure out what to do and decide hey let's try having sex with a man! I can't be sure how it works on the straight side as I've never experienced it, but i don't imagine many straight men would just decide they should go fiddle around with their buddy.
this notion of choice does not comport with my experience and i don't know where it came from (bisexual preachers perhaps?). so the notion that i'm somehow a bad person, due to something i had no control over just strikes a nerve i guess. i know you all have that whole original sin, but apparently i got two! that's not fair, what happened there? is god just pulling my chain?
i've never been given a satisfactory answer to that question somehow. but i mean human sexuality is a pretty complicated nuanced area of academic study, so i try not to expect too much out of a fairly young middle eastern religion like christianity.
it wouldn't bother me so much if some christians weren't so gung ho to attempt to legislate their version of sharia on me.
