It’s a peaceful protest.
No need to be quite so public. Simply walk across the symbol of hatred (of anyone who engages in “wrongthink”) and dribble powered ink that turns dark and permanent when morning dew rolls in. Or, printer toner powder.
The pride crappola is a symbol of hatred. No less than a swastika. It does not proclaim that “we are united, we are inclusive”. It says “you are wrong and watch how we get to tell the world that”.
