I tend to think the best option is if there’s two flag poles is the original Pride flag and the trans flag should be flown to show solidarity. But either progress flag is good when you don’t have space, I’m flying a progress flag right now.
The Pride flag by itself has been co-opted by capitalists and some TERF organisations. So seeing one by itself can be suspicious.
(Also only tangentially related I think the gay flag with the pink triangle on black and the lesbian flag with the black triangle axe and purple background go much harder than the newer progress flags for those groups)
I actually really like the way that the Chevron breaks up the stripes of the rainbow. However, a better designed flag would make the chevron a single color.
Before he died, Gilbert Baker suggested adding a lavender stripe for Diversity to the rainbow flag. I say make the Chevron a single lavender color.
In lieu of that though, I like the progress flag in the way that I like the flag of Maryland. It's so bad it loops back around to being charming.
If I want good queer flag design, I'll go to the bi, trans, and intersex flags. Most everything else is garbage tbh. For a group of people stereotyped as having an eye for aesthetics, we're garbage at flags.
