I don't understand why it is important for me to care if a terrorist is Muslim or not. I mean, I'm even willing to grant that all terrorists are Muslim so that it will just go without saying and no one tries to remind me. Why does it matter?
Similarly, atheists sometimes love to talk about bad things that have been done in the name of Christianity. Don't care. Doesn't matter.
So you're not a trend spotter. That's okay.
If someone can explain the point, maybe I will be!
It's significant when it comes to crafting immigration policy, for starters. France is getting their crap kicked because of their asinine immigration policies that permitted large blocks of Muslims to immigrate en masses and thereby not assimilate. Islam + non assimilation = radicalization.
We have the start of a similar problem. See the radicals spawned by the St. Paul MN muslim community. Meanwhile, Obama is trying to import tens of thousands of refugees from Muslim countries. There will be some bad apples who slip through in this group, but the bigger problem is their children when they don't assimilate.
There are also broader foreign policy consideration when it comes to combatting terrorism. It's a good idea to at least acknowledge that a certain culture is spawning most terrorism and adjust accordingly.
But to liberals, this is all "xenophobia."
