Agreed.  It's hard to respect the poster's clear ignorance of history, when "Europe" only exists because multiple Hunnic, Mongol and Islamic invasions of that continent were turned back. 

 Every time I see a post like this, I want to physically fly the poster over to Vienna so they can see the plaque and monuments to the defeat of the Ottomans on the doorstep to Europe in the 1500s, or to Tours so they can see exactly how far into France the Umayyad Caliphate got before being turned back by Charles Martel in the 700s. I guess those of us in western culture should feel guilt for our ancestors ... winning? 

Don't even get me started on the predations of the Zulu on surrounding tribes, or the domination of Meso America by the Aztecs.
