If one starts with the premise that there is something to fear, then your points are good ones.

But to track the Harvey Milk analogy, there was a time when a good deal of the hetero community feared that they, or their children, might be perverted (or worse) by exposure to gay folk.  They might reasonable have feared priests, but I digress.  

Harvey's great insight was that knowing more gay people in your otherwise hetero life would help defuse that fear, and allow the hetero community to accept and even embrace a community that had once been a pariah.  No one needed to get into too much detail about what might be called the 'teachings' of gay life for that process to gradually start happening.

With Muslims, maybe there is something to fear, like reproduction fuelled world domination or some other militaristic caliphate-centric agenda.  But if there isn't, maybe "getting to know each other" is as good a start as any.   There's still time to act, if fear is warranted.
