In 1978, San Francisco artist Gilbert Baker designed the Freedom Flag.
Always flown with the red at the top (or left hand side, if vertical), the flag celebrates diversity in all its forms. Everything within it is equal, merging into one.
Baker chose a rainbow because it occurs in nature; and it places all hues in perfect harmony.
A generation of LGBT people have made the Freedom Flag their own. All over the world, through the work of Gay Pride, onlookers link this rainbow with them.
It's tribal. It's about self-identity. It's about taking your place in nature and not letting anyone play God with what is. In many countries, it still remains the banner under which people fight for their civil rights.
Yet they're also looking at the bigger picture of equality. Red isn't better than orange. Neither take precedence over purple. However nature made us fits brilliantly into the whole ensemble. Like a rainbow; like the world should be.
And what better Christmas message than that? Peace and goodwill to all.
