there should be no decorations on municipal crosswalks
You could make an argument that crosswalks should be painted a standard colour with expected markings, since it's a safety/accessibility issue that that point.
or displaying of flags supporting political, social, or religious movements or commercial entities
The people who put the package together lumped everything into the same category.
Sure, we should NOT have religious flags on our government buildings. By that token, we should remove any and all religion from those buildings and any texts, too. No mention of God, especially.
Commercial entities? Yeah, they don't belong on government flag poles.
Political? I'd need an example. I would not want to see the flag of various parties on a government building. That's just inappropriate.
But social movements? They stay. I WANT my local, provincial, and federal governments to show support for marginalized groups. That includes our LGBTQ, indigenous, disabled, visible minorities, etc.
I'm proud to see our local fire and police vehicles with rainbow flag stickers on them.
Separate the hate from the reasonable, and this petition might not seem so ass backwards.
