As a straight guy who supports human rights for LGBTs, This is a terrible idea and would make a total mockery of it. This will be resisted by most LGBT that I know.
What supposed “rights” do you support for “LGBTs” that they don’t already have?
Out of curiosity, is same sex “marriage” a “ human right”? I can see equality under the law... civil unions...but it seems the other is just a swipe at religion. I know some will argue that either is a swipe at God.
Their “rainbow” is cultural appropriation.
