I apologize for this long comment.
I've never owned any pride flags, yet, but a little voice did once say something in my head when I was considering that fact, and what flags I would fly. "What would your flag be?" Flags get made for all sorts of things... stuff that doesn't even really deserve them like countries. Why shouldn't there be flags for important stuff like one's self. I didn't really know enough about myself at that time to answer the question of what my very own flag would be. But being uncertain about it wasn't what made me stop thinking about it. It was when another voice piped up and asked, "But would you even fly it if you knew?" And I didn't have an answer to that either, which hurt more, for me at least, than not yet knowing myself well enough to form even a clumsy visual symbology of "ME" It brought to the forefront the idea of the purpose of a flag being to make a statement with a sort of label. And that cuts both ways. The desire for the world to see ME but also the dread of not being accepted and the negative repercussions that would come along with that. And it also brought up the thought of a flag for me that no one else could recognize the meaning of, positive or negative, and how pointless that would make me feel.
But symbology, the meaning of symbols, is literally what we make of them. And the importance isn't always in conveying the message to others but one's self. I discovered "The Three Hares" symbol/motif some time back (I found it randomly for obvious reasons). The three hares is a motif that seems to have originated in Buddhist temple caves in China and traveled/spread from there through the middle east (possibly due to the silk road) and, likely with the ever present "aid" of colonialism, into Europe. The original "official" meaning of the motif seems to be lost to time, and the meanings attributed to it by various people since then often differ greatly. It acts as a visual puzzle, a religious symbol for multiple religions, and more, often using the different culture's symbology around rabbits/hares to inform their own meaning... which are sometimes similar (fertility pops up often), but different enough to rarely share the same full meaning over distance/history.
So many different people placing their own meanings on this motif across the ages (including the meaning I added for myself) spoke to me in regards to that original question on self representation. It's impossible to control how other people see you, positive, negative, or indifferent. Negative consequences will exist, and only shrink over time as compassion and well informed understanding, or just indifference, begins to spread more. But the question of self is only up to each of us individually, and those outside of ourselves should have no bearing on the answers. And there are answers there, even if we aren't aware of them all at once.
You have those flags for a reason. I would guess you see part of yourself in them. Belonging and aspiration dwell there. Those feelings are deserved. You owning or flying them is a recognition of the existence of that person. Even if you don't fly them at present, you deserve to. You are you, always and forever, no matter what new lessons you learn on your journey.
That was my own meaning I gave to the three hares; the journey.
