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.
There are a bunch of places in SE Michigan that has a large Muslim population. Michigan has more Arabic-language speaking people in it than any other US state.
Yet it’s only the Christians who freak out about this. For a while there was a bizarre rumor being spread by Christian bigots that Dearborn, MI, which (last I knew) has even more Muslim people than Hamtramck, was run by a Muslim mayor with everyone forced to live under “Sharia Law.” The mayor was Protestant and there is no place in Michigan where Muslim religious law is part of the area’s laws.
