Greater Manchester Police is flying the flag for an international event to raise awareness of prejudice against gay and transgender people.And what about all the other political single-issue organisations? If they have flags, will you fly them too?
The force is flying a rainbow flag above its Chester House headquarters.
You are pretty much going to have to now, aren't you? You've opened the door:
Mr Fahy said: "This shows Greater Manchester Police's commitment to ensuring people, whatever their individuality, can feel safe in the city.Good for you, but you are the police. You do that by arresting people who have broken the law.
"Every day a number of hate crimes are reported to us, which I always find alarming.
"Whether people are gay, disabled, black, Muslim or Jewish, we find that there is a level of abuse directed at them.
"This tells us that there is still a great deal of prejudice and hatred out there, but we are determined to show our support for anyone who feels they have been targeted because of their individuality."
Not by gesture politics...
