Some of those are bloody disrespectful. Some are very brave.
I'm not too big on dissing, or dismembering, an entire religion. I believe too much in diversity-- and know there is too much diversity within any large demographic-- to be OK with that.
But. The following are hypothetical situations that could realistically arise or have arisen in my life:
I consider myself a Christian. If I were a churchgoer and some friends at my church say they wish the US were a Christian theocracy, I should be leery of those people and strive to prevent their ideology from spreading. If they begin planning a militarized effort to turn the US into a Christian theocracy, I have a duty to stop them by saying something to authority. If they tell me they are going out in the morning to blow themselves up in a Planned Parenthood clinic, however much I despise PP, I have a duty to stop them from making any farther progress, immediately, by citizen's arrest if necessary.
If I allow them to spread those beliefs, or go through with those actions, I can expect people to not be too happy with Christianity. If it happens often, I can expect to be suspected and persecuted simply because I am Christian.
Not so long ago, I considered myself a Pagan. If some of my friends had argued that coercive ritualized sex increased one's magical power, I would have been obligated to counteract that ideology and be leery of those people. If I overheard them making plans to lure vulnerable young people into a cultic environment, I had an obligation to inhibit those plans from bearing fruit by alerting authority. If, on the previous day, I heard them planning to commit a gang rape on Samhain night, I had an obligation to go immediately to the authorities and stop them from making any farther progress, as above.
If I had chosen to allow them to spread those beliefs or carry out those actions, what could I have expected my reception as a Pagan to be??
IS is turning the non-Islamic world against Islam, because IS is by definition against the existence of the non-Islamic world. That is the nature of militaristic dominionism, and that is why militaristic dominionism, past a certain point (the Christian Patriarchy movement in the US is precariously close to teetering on the precipice of that point, and some radical Christian dominionists have already slipped over), cannot be tolerated. To quote a cliche, "You can't coexist with people who want to eradicate you."
Muslims and former Muslims have a choice: stop the ideology and the actions, or end up getting tarred with the same brush and possibly sharing the same fate. I'm sorry about that. Sincerely. It makes me very, very sad, because I am a moral and moralistic woman of idealistic tendencies and black-and-white perceptions and therefore have an extremely hard time reconciling that in my conscience.
But there it is.
