I also think the Progress Pride Flag represents conduct and actions I view as sin. Not like, gender/sexual sin. Design sin.
The rainbow flag was already perfect. The rainbow flag to me says "human behavior exists on a spectrum, and everyone matters". It's beautiful, elegant. The stripes don't represent distinct groups, though sinners (the flag redesigners, not LGBTQ+ people) have tried. The flag itself represents harmony in diversity. You can't get better than that, no notes.
The Progress flag is meddling with a perfect formula. It takes a perfect symbol to celebrate diversity itself and plasters it with footnotes. By highlighting specific groups that were included by the rainbow in the first place, it just opens the door to more and more complex revisions to include more and more distinct groups. It turns a poignant symbol of broad inclusiveness into a weird patchwork of granular inclusiveness. That would seem like hyperbole if the pictured flag wasn't already the intersex-inclusive revision.
It's just sloppy vexillology. The rainbow flag is awesome. Why are we fucking with it?
