Reasoning showing homosexuality is evil.

[WinterHold]

Where is the verse in the Quran?

Well, I've found these:

What! Of all creatures do ye come unto the males, And leave the wives your Lord created for you ? Nay, but ye are froward folk.--26:165-6
Homosexual acts are condemned as unnatural. (Will ye commit abomination such as no creature ever did before you?) 7:80-81
Male homosexual activities are condemned as unnatural. 26:165-6
Male homosexuals commit abominations and act senselessly. 27:54-55
Male homosexuals acts are condemned as unnatural. 29:28-29

Doesn't seem to be much against lesbianism.

The story of the people of Lot is mentioned 

Sura 7, The Quran:
( 80 )   And [We had sent] Lot when he said to his people, "Do you commit such immorality as no one has preceded you with from among the worlds?
( 81 )   Indeed, you approach men with desire, instead of women. Rather, you are a transgressing people."
( 82 )   But the answer of his people was only that they said, "Evict them from your city! Indeed, they are men who keep themselves pure."
( 83 )   So We saved him and his family, except for his wife; she was of those who remained [with the evildoers].
( 84 )   And We rained upon them a rain [of stones]. Then see how was the end of the criminals.

The story is mentioned too in:

Sura 27, The Quran:
( 54 )   And [mention] Lot, when he said to his people, "Do you commit immorality while you are seeing?
( 55 )   Do you indeed approach men with desire instead of women? Rather, you are a people behaving ignorantly."
( 56 )   But the answer of his people was not except that they said, "Expel the family of Lot from your city. Indeed, they are people who keep themselves pure."
( 57 )   So We saved him and his family, except for his wife; We destined her to be of those who remained behind.
( 58 )   And We rained upon them a rain [of stones], and evil was the rain of those who were warned.

A third time also in:

Sura 29, The Quran:
( 28 )   And [mention] Lot, when he said to his people, "Indeed, you commit such immorality as no one has preceded you with from among the worlds.
( 29 )   Indeed, you approach men and obstruct the road and commit in your meetings [every] evil." And the answer of his people was not but they said, "Bring us the punishment of Allah, if you should be of the truthful."
( 30 )   He said, "My Lord, support me against the corrupting people."
( 31 )   And when Our messengers came to Abraham with the good tidings, they said, "Indeed, we will destroy the people of that Lot's city. Indeed, its people have been wrongdoers."
( 32 )   [Abraham] said, "Indeed, within it is Lot." They said, "We are more knowing of who is within it. We will surely save him and his family, except his wife. She is to be of those who remain behind."
( 33 )   And when Our messengers came to Lot, he was distressed for them and felt for them great discomfort. They said, "Fear not, nor grieve. Indeed, we will save you and your family, except your wife; she is to be of those who remain behind.
( 34 )   Indeed, we will bring down on the people of this city punishment from the sky because they have been defiantly disobedient."
( 35 )   And We have certainly left of it a sign as clear evidence for a people who use reason.

Now; read these verses with the eye of a critic and tell me: where is it mentioned that homosexuality is evil?
Rather; it seems like the people of Lot (both men and women) used to obstruct the roads (probably kidnapping people?), raping males, and commit evils which aren't mentioned in their meeting places.

But where in the verses above, is it mentioned that you should kill gays?
or more so: where is it even mentioned that it's evil? it's a sin; it's ignorance, it's "lavish"; but evil ?

The Quran is clean on killing homosexuals; there is not even a single verse. As for God torturing and punishing, gives no right for people to play God and kill and torture, that's a divine right. And God is killing us all the time if you think about it; all of us die.

Makes our life; takes our life.
