Dude - what the fuck?
I am no fan of religion, especially where people try to force it down others' throats and immeasurably more so when that is done at the point of a sword. (Barrel of a gun, threat of a noose, lash of a whip - whatever . . .)
BUT, your post, whether representative of your views or not, is hideous.
What needs to be stopped is the process of radicalisation that is occurring. For that to happen, we must first understand why it is occurring. There are so many reasons but the primary one appears (to me) to be that there are large groups of people, the world over, who are angry with modern world or simply feel that they don't belong in it.
Whether that's because they had their homes destroyed and families and friends killed through the continuation of centuries or internal violence or misdirected western munitions or, for those in more 'peaceful' countries, they might simply be disillusioned with the world - brought up in impoverished neighbourhoods without much in the way of job prospects, feeling like they've been forgotten and no one cares. They may feel they have no identity and no purpose or power so they are drawn to a group that will give them an identity and give them a purpose and give them power.
Some of them, of course, have simply been indoctrinated from their earliest years - taught to hate and not to question; taught that they are the chosen people and everyone else is against them and against their god; that they are besieged and called to be free and to free to world in turn.
It's not that it is your fault or my fault or the fault of some western politician; it's that whatever the causes are, we need to understand them so we can work to fix them.
Yes, we have reached a point where tough decisions are required to arrest this juggernaut and yes, people are going to die. To put a finer point on it: those looking to halt the wave of religious-imperialist violence will need to kill people to do so - just as has been required every time this has happened in the past.
BUT, there are two crucial points.
The first is that we should do so with heavy hearts rather than exulting in the violence and death; we should lament that such extreme measures have become necessary.
The second is that, while violence is indeed necessary if this tide is to be stopped, it is not sufficient in and of itself. We must cut off the source of these radicals and that means understanding why they joined these brutal, intolerant, hateful groups.
No part of the 'solution' involves mass gas ovens and especially not live streaming and glorification in barbarity - if you haven't been paying attention, that's the thing we are trying to stop.
