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.
Your comment is talking about Christians and Muslims in general, there’s nothing in there that indicates you’re talking about the population in a specific country. Nor is the comment you’re replying to referring to a specific country.
Even giving you that, I find it hard to believe. The only reason the Muslims aren’t behaving as you say the Christians are is because they don’t have the authority or force of numbers. Name a single religious majority worldwide that doesn’t push their values onto nonbelievers.
