Homosexuals do not help the needy according to Ezekiel and so that helps them accrue wealth.
Ezekiel 16:49-50 (KJV) Behold, this was the iniquity of thy sister Sodom, pride, fulness of bread, and abundance of idleness was in her and in her daughters, neither did she strengthen the hand of the poor and needy. And they were haughty, and committed abomination before me: therefore I took them away as I saw [good].
The rainbow does not belong in any sense to the homosexuals. The word bow in Scripture, as I understand it, comes from the Hebrew word for the weapon bow as in bow and arrow. The bow is aimed at Heaven, indicated that the next one to pay the price for the sin of man would be Jesus and Jesus paid it all.
The destruction of mankind in the worldwide Genesis Flood except for Noah and his wife and their three sons and their wives did not stop the sinning of mankind and did not change the sinful nature of mankind.
Genesis 9:13-15 (KJV) I do set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, when I bring a cloud over the earth, that the bow shall be seen in the cloud: And I will remember my covenant, which [is] between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh.
