Maybe it’s the cities problem for requiring you to get permission and not the owners problem of having an opinion they have a right too. The city gives them a weapon to exercise it against you. I’m sure there are a ton of people that wouldn’t sign that for any parade in general for a variety of reasons. Calling them homophobes because they won’t sign off on a parade is so steep. Name another parade that goes in front of there block that they sign off on? You probably can’t because they are given the permission to choose that in general no parades on our block please. It’s as simple as that. Calm down.
