I can’t say I blame them for feeling betrayed but Islam like the majority of the Christianity leans to the conservative side socially when it comes to sexuality and gender identity. They shouldn’t be surprised when an all Muslim majority city council starts to act on their belief system and enact ordinances that run against the more socially liberal citizens.
If you look at my comments elsewhere, you’ll see I was confused by the title (which I think implies it’s banned everywhere in the city) but then later mentioned the article specifies “on city property”. The title is needlessly (and probably intentionally) confusing.
