I agree in principle and those things you mentioned are there and are objectionable (though as you say, some edit certain things out or don’t really implement them in practice - I’ve known Muslims who drink, for example, even though alcohol is supposed to be banned by Islam as well).
It is curious how Islam has been taken up by the PC left as a sort of protected category, on par with other pet causes, even as officially Islam is diametrically opposed to most of the standard left agenda (gay marriage, transgenderism, etc., to name just two). I guess they simply see them as a convenient minority within the West they can use as needed to bash the right, while overlooking things like repression of women, honor killings, executions of homosexuals, anti-Semitism, etc. in actual Muslim-ruled countries (things the Left would never countenance if they occurred in their own countries, and rightly so).
