Symbols of Pride
There are many widely recognized symbols of Pride that have been used by LGBTQ communities over the years:
Some symbols are explicitly for GayPride while others just indicate homosexual (etc.) status. In sexualized symbolism, there are the HankyCodes (indicating sexual preferences for sex between men).
There are many other symbols of pride/queer identity. Please add as needed.
