I did something shameful.
I would sometimes drive to the closest major city that had a large queer community (multiple times) with my rainbow sticker on (it was one where you can just peel it off) and took it off when I drove back home to my smaller town.
I work for a Catholic School Board. (which is actually PUBLICLY funded due complicated reasons). I still burn with redness that I actually reached back and peeled it off before I hit my city--my apt. was very close to my school at the time.
There's more shame than that but I wanted to share that feeling of peeling off the sticker--when I had my first queer relationship--so NO ONE would KNOW that I had a female lover.
Thanks for sharing your stories of rainbow/queer stickers or visible signs of being part of the LGBTQI community.
