If a line was formed facing you and your family, each person armed and with the intent to kill you and your family, and you with superior weaponry to protect your loved ones.
The question begging an answer is: how judicious would you be in screening the threat, knowing that you could eventually be overwhelmed, and that your family would be tortured before being killed?
That's an unlikely hypothetical. You're wanting all of a group killed in order to insure some of the group who want to kill you is eliminated.
I spent 3 months in Kyrgyzstan, one in Kazakhstan, and two in Albania. What they all have in common is that the majority in each country are of Muslim heritage. They also were all communist countries. The communists more or less beat religion out of them. So much so that those practicing Islam or Orthodox Christianity, the dominant Christian sect in that part of the world, are in the clear minority. Women whose great-great-grandparents were devout Muslims walk around in Western clothing including pants, with their heads uncovered. No veils. Did see some of that in Kyrgyzstan, but most weren't. I felt no ill will. Most were very friendly and were curious why I came to their country. Do you know what I hear when I recount my experiences here? That I'm naive. That they're evil. Were communists too. I saw first hand people embracing capitalism and it was expressed many times how much they hate the Russians and love the U.S. But people here, influenced by commentators after 9/11, believe they are all in lockstep to conquer and/or kill us. Make no mistake about it, there is a very sizeable percentage of Muslims who'd like nothing better than to kill us or at least conquer us and force subservience on us. But spend time in those countries and you'll soon realize that the only connection most have to Islam is that their families once practiced it. Not any different than how many today in Europe and the U.S. are no longer practicing Christians and their families haven't been for generations. But people here will forever consider them tainted. Fear. They run with the most unlikely scenarios. It's easier. How do you convert someone to Christianity if your solution to Muslim extremism is to kill them all? And how do you face God someday after doing that? What a world we would live in where a 5th of humanity is hunted down and eliminated.
