Looks like the LGBT+ activists have never read Genesis 9. As Ken Ham notes: Jews and Christians had a claim on rainbows long before the LGBT+ crowd appropriated it.
Well, I do agree that some people are trying to “poison the original intent of the rainbow” — but it’s not our Ark Encounter! (Today’s letter in the Enquirer newspaper of Cincinnati.)
“And God said: “This is the sign of the covenant which I make between Me and you, and every living creature that is with you, for perpetual generations: I set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth. It shall be, when I bring a cloud over the earth, that the rainbow 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; the waters shall never again become a flood to destroy all flesh. The rainbow shall be in the cloud, and I will look on it to remember the everlasting covenant between God and every living creature of all flesh that is on the earth.” And God said to Noah, “This is the sign of the covenant which I have established between Me and all flesh that is on the earth.” (Genesis 9:12–17)
