I like how all the evidence I've provided is "small" (and it was only a tip of the iceberg of demographic stuff), and you guys are dismissing it with a grand total of zip other than doing the "look around" test and goin "Nope, don't see any Sharia here", as if we are talking about something that would happen now, or tomorrow, or even twenty years from now.
Obviously a ton of different things could happen in a time-span like 100 years or more that that could change trajectories, like war, resource shortages, etc. That's not being debated. But, what's under contention is pretty clear cut: Islam is growing biologically and through conversion. Europe and the US are graying. Europe and the US also have also been stripped to some degree of defense against aggressive behavior because of SJW bs (like neighbors not reporting the Cali bombers, UK keeping all the rapes hush hush, Germany trying to keep a lid on the NYE stuff, etc), and against conversion because of atheism. If policy, fertility, and religiousity continue to go as they currently are, at some point in a future (very likely past our lifetimes), the Muslim population would reach the critical mass necessary to make various countries Islamic by default, and other places create a voting/political bloc powerful enough to push various things through. If you think some of those trends will not continue, how about which one(s) and why/how (with some actual support), rather than going "lulz build a bunker bro". Or simply don't say anything at all.
