To celebrate the opening of the newly painted Pride crossing on the road. The crossing symbolises that gay, straight, queer, lesbian, bisexual are who we are. It wasn't actually the sexual orientation of the person crossing the road that mattered right?It was that there is a community, a safe and comfortable place for everyone to be who they are.
If this is true, I'm a little disappointed with the OP and, to be fair, myself for laughing at some of the 'jokes'.
