Behold,this was the iniquity of thy sister Sodom, page 1

Disclaimer: I'm a theist but not of the Abrahamic faiths. I have minor biblical scholar and scriptural skills. Also I am not a scientific/legal or medical expert in any field. Beware of my Contagious Memes! & watch out that you don't get cut on my Occams razor.All of this is my personal conjecture and should not be considered the absolute or most definitive state of things as they really are. Use this information at your own risk! I accept no liability if your ideology comes crashing down around you with accompanying consequences!

Explanation:- 1stly the OP states and I quote it directly "Chapter 1 of Romans can be linked to this.

Verses 21-27 talk of how they left God to worship another,and how they behaved when worshiping this god;sacred prostitution etc.Verses 28-32 talks of how they behaved in everyday life.This is made clear in the fact that,in the former verses mentioned,only sexual acts are mentioned.
Whereas in the former verses non-sexual acts and emotions are mentioned in abundance."

This makes no sence as there are 2 instances of the word "former" and these lead to a contradiction and do NOT make an accurate description of the scripture that the OP quotes. To fix this I suggest it be read as follows "This is made clear in the fact that,in the former verses mentioned,only sexual acts are mentioned. Whereas in the LATER* verses non-sexual acts and emotions are mentioned in abundance." NOTE: *= my FIX!

2ndly the OP states and again I quote it directly "It is said that the sin of sodom was homosexuality.Common sense tells most people that wanting to gang rape a man does not make you a homosexual."!!!

PROMOTING IGNORANCE WILL GET YOU NOWHERE!!! So to DENY this I provide
the following evidence :
LINK
Evidence from LINK is as follows....
"The earliest discussions of male rape in prison are found in the correctional literature dealing with homosexuality. These works (Buffum, 1972; Clemmer, 1958; Fishman, 1951; Kirkham, 1971; Sagarin, 1976; Sykes,1958) focus on creating topologies of homosexuals. Most of this body of research, like other research on sexuality during this era, employed an essentialist theoretical approach. According to this perspective, sexual orientation is a static and permanent characteristic, and people can be categorized into two dichotomous groups—heterosexual or homosexual (see Eigenberg, 1992). This approach does not accommodate bisexuality, nor does it recognize the possibility of a changing sexual orientation. As a result, most of the early literature on prison sexuality concentrated on discriminating between “true” and “situational” homosexuals"..... Situational or not they are still HOMOSEXUAL!!!

Besides YHVH through Moses isn't ambiguous on this at all:-
Lev 20:13 If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood [shall be] upon them.

YHVH certainly doesn't care whether its situational or not or whether anybody enjoys themselves or not or whether they consider themselves homosexual or not. He says if you do it at all ever then you are to DIE! (I have found NO caveats to this in the Old Testament as yet!).

Now I'm not dodging your question so here is my answer " Yes, if I was of the Abrahamic faiths then I would have to question the Gibeah issue and resolve it, but I'm not so I have no need to do this!"

3rdly The OP states and I quote directly "Proverbs 6:16-19 (homosexuality not mentioned)

These six things doth the Lord hate:yea,seven are an abomination unto him:A proud look,a lying tongue,and hands that shed innocent blood.An heart that deviseth wicked imaginations,feet that be swift in running to mischief.A false witness that speaketh lies,and he that soweth discord among brethen". Would not a homosexual scriptually be considered to be
"An heart that deviseth wicked imaginations"(i.e. wicked imaginations =practicing homosexuality) whose "feet that be swift in running to mischief"(i.e.mischief= practicing homosexuality) and are "he that soweth discord among brethen"(i.e. by practicing homosexuality!)???

4th and finally the OP asks "The sin of Jerusalem,homosexuality??" and I reply that if you look very carefully at the scripture provided it shows its the Prophets of Jerusalem and the evil doers and not Jerusalem "Herself" that sins and yes the sins of the False prophets and the evil doers could quite concievably include homosexuality!

Personal Disclosure: I have no problems with any legally allowed sexual orientation or with the entities who have such sexual orientations. Do what thou will and HARM NO ONE!
